Fault messages in the Package Manager window

The Package Manager displays error indicators in the Package Manager window when information technology encounters problems:

• Organization-wide bug

  Error letters that announced in the status bar indicate the Parcel Manager has detected an event that is non related to a specific bundle. For example, if the Package Manager cannot access the package registry server, it displays this message in the status bar:

  

  Network error message

  If your network cannot reach the package registry server, it is probably because there is a connexion problem with the network. When you or your system ambassador set up the network fault, the status bar clears.

  If your network connection is working, only you are not signed into your Unity account, the Parcel Manager doesn't brandish whatever Asset Store packages. When you try to apply the My Avails context, the Package Managing director displays an mistake in the status bar:

  

  Logged out of Unity business relationship

  Click the Sign in push button inside the list view to sign into your Unity account through the Unity Hub.

• Bundle-specific problems

  If a specific package has a problem when loading or installing (for example, when determining which parcel versions to load), the error icon () appears in the parcel list side by side to the compromised packet (A). To find out what the trouble is, open the compromised package's details view to see the detailed error message (B):

  

  Dependency error bulletin

Packet Manager missing or window doesn't open up

The Parcel Manager window might get moved offscreen or subconscious by another window. When this happens, it looks similar the Parcel Director window failed to open. In this example, y'all can try to reset the window layout (Window > Layouts > Default) and reopen the Package Manager window once more.

If the Package Manager window still doesn't appear, bank check your Unity Console window A Unity Editor window that shows errors, warnings and other messages generated by Unity, or your own scripts. More info
See in Glossary :

          Failed to resolve packages: The file [<project-path>/Packages/manifest.json] is not valid JSON:   Unexpected token '}' at 44:i   }                  

This mistake message indicates that your manifest.json file is malformed. It as well tells y'all the line number where the Parcel Managing director failed to parse the file, then y'all can fix the JSON. There are a number of online validators that you can use to attempt to correct the problem. In one case you save the corrected file, Unity reloads the Package Manager window.

If y'all upgraded from an early version of the Unity Editor, there may be other problems with your package manifest Each package has a manifest, which provides information about the package to the Package Manager. The manifest contains information such every bit the proper name of the package, its version, a description for users, dependencies on other packages (if any), and other details. More than info
Run across in Glossary file:

• As of 2019.three, your manifest.json file should not contain any references to the com.unity.packet-manager-ui bundle. You can either reset your project'southward bundle configuration or remove the following line from the manifest'southward dependencies list:

                                "com.unity.bundle-manager-ui": "2.1.one",                          

• Check to see if your project manifest Each Unity project has a projection manifest, which acts every bit an entry point for the Package Manager. This file must be available in the <projection>/Packages directory. The Packet Manager uses information technology to configure many things, including a list of dependencies for that projection, besides as any package repository to query for packages. More info
  See in Glossary uses "exclude" as a bundle version. This is an obsolete value for the dependencies
  See in Glossary belongings. If you find any lines like these, remove the entire line. Package Manager but installs packages that are explicitly included every bit a dependency in your projection, then once you remove that entry, Packet Manager ignores the package and doesn't install it.

If the Package Manager still fails to load, follow the procedures under Packages not recognized and Resetting your projection'south package configuration.

Problems after upgrading Unity to new version

When you upgrade a projection to a newer Unity version, the Package Manager automatically updates incompatible packages to newer compatible versions. However, if your package doesn't compile, the Package Manager displays error letters in the Console.

To correct these messages, read the error messages and set any issues you can. For example, a packet might be missing a dependency on another package or version. In that case, you can try and install the packet yourself.

You tin can too attempt the following sequence of solutions until you observe something that works:

• Back upwards and and then delete the Packages folder nether your project.
• Support then delete the parcel sources in your project's Packages folder, leaving only the manifest.json file. So try to reload the project.
• Create a new empty project. If the Package Manager window loads successfully, replace the Library/PackageCache/com.unity.package-director-ui@<version> binder in the declining project with the aforementioned folder from the newly created projection.
• As a last resort, you can reset your project to the default parcel Unity automatically pre-installs a select number of default packages (for example, the Analytics Library, Unity Timeline, etc.) when yous create a new project. This differs from a bundled parcel because you lot don't need to install it and it differs from a built-in bundle because information technology extends Unity's features rather than beingness able to enable or disable them.
  Run into in Glossary configuration and add back packages ane at a time until it works.

Resetting your projection's package configuration

If a project has besides many package bug, you lot can reset your projection back to the default package configuration for the Editor'southward version of Unity. This performance resets all packages in your projection. This might not fix the source of the problem, just it can assistance you figure out what the problem is.

Note: You tin can't undo resetting your bundle configuration, so make sure you back upward the manifest.json file beginning or make sure your project is nether source control. You tin also take extra precautions past cloning your project and testing out the operation on the clone earlier proceeding.

To return to the default package configuration, select Reset Packages to defaults from the Help menu.

Help > Reset Packages to defaults

Resetting a clone of your project

Yous can also test the render to the default packages before you perform the final change:

1. Clone your project by re-create-pasting your project folder and renaming it so that it is like shooting fish in a barrel to find (for instance, if your project is called MyProject then you could use something like clone_MyProject).

2. Load your newly cloned projection.

3. From the Help carte, select Reset Packages to defaults.

   Depending on the size of your project, this might take a few minutes.

4. Check that information technology successfully reset the packages. If so, you can perform the operation safely on the original project.

Package installation fails

If you are trying to install a new package from the registry and it is not working, information technology might be due to permission problems.

Yous must have full permissions on the enshroud binder:

• Windows: C:\Users\yourname\AppData\Local\Unity\cache
• MacOS: ~/Users/Library/Unity/cache

Information technology might be a problem with the network. Check your firewall and proxy settings.

Sometimes institutional environments, such as schools, authorities offices, or network-protected workplaces fix proxy servers to command traffic between the network and the Cyberspace, and use their ain server certificates which are not recognized by Unity or the Package Manager. Talk to your network ambassador.

Packages not recognized

If you meet a lot of compilation errors, this might indicate that Unity is not recognizing the packages in your existing projection. In this case, you lot might be missing a .Cyberspace component.

For Windows:

1. Download and install Visual Studio 2017 version 15.ix.0 or higher with the .Cyberspace Cadre cross-platform evolution workload selected under Other Toolsets.
2. Download and install the .NET SDK v2.ii.101 component.

For MacOS:

1. Download and install the .Cyberspace SDK v2.2.101 component.

2. Install any recommended updates in Visual Studio

3. Utilize homebrew to brew and install mono:

                 brew update brew install mono # optional mash upgrade mono                          

4. If necessary, delete the Library/obj/temp folder under your project and restart Unity.

5. If you lot are still experiencing difficulties, try rebooting your reckoner as well.

No 'git' executable was establish

If you lot try to install a packet from a git URL, a message like to this appears:

          Cannot perform upm performance: Unable to add bundle [https://github.case.com/myuser/myrepository.git]: No 'git' executable was establish. Please install Git on your organization and restart Unity [NotFound] UnityEditor.EditorApplication:Internal_CallUpdateFunctions()                  

git-lfs: command not constitute

If you are trying to download a package that uses Git LFS (Large File Storage), you might encounter this error message:

          Error when executing git control. git-lfs filter-process: control non found.                  

This indicates that Git LFS is probably not installed on your machine. To brand sure, you could examination it on the command line:

          git lfs --version                  

If yous see something like this, Git LFS is installed:

          git-lfs/2.eight.0 (GitHub; darwin amd64; go i.12.vii)                  

Otherwise, you tin can install information technology past following the Bitbucket GitHub instructions.

Repository not constitute

If y'all specify a location that does not exist, a bulletin similar to this one appears in the Unity Panel:

          Cannot perform upm operation: Unable to add together parcel [https://mycompany.github.com/gitproject/com.mycompany.mypackage.git]:   Error when executing git control. fatal: repository 'https://mycompany.github.com/gitproject/com.mycompany.mypackage.git/' not institute  [NotFound] UnityEditor.EditorApplication:Internal_CallUpdateFunctions() (at /Users/builduser/buildslave/unity/build/Editor/Mono/EditorApplication.cs:310)                  

Check your spelling. To make sure y'all are using the correct URL, go to the repository's page and copy the URL from the Clone button:

Where to copy the URL on GitHub (A) and GitLab (B)

Click the button to the right of the URL on GitHub (A) or GitLab (B) to re-create the URL to your clipboard.

If the location of the repository is correct, there may be some other problem with the URL:

• If you are targeting a specific revision, make certain your revision comes terminal. For example:
  https://github.example.com/myuser/myrepository1.git#revision
• If you lot are targeting a revision and the package is not at the root, brand sure the path query parameter precedes the revision anchor. For example:
  https://github.example.com/myuser/myrepository.git?path=/example/folder#v1.2.three

Could not read Username: terminal prompts disabled

If y'all are trying to install a packet from a private repository that requires hallmark, a message like to this one appears in the Unity Panel:

          Cannot perform upm operation: Unable to add bundle [https://mycompany.github.com/gitproject/com.mycompany.mypackage.git]:   Error when executing git command. fatal: could not read Username for 'https://mycompany.github.com': last prompts disabled  [NotFound] UnityEditor.EditorApplication:Internal_CallUpdateFunctions() (at /Users/builduser/buildslave/unity/build/Editor/Mono/EditorApplication.cs:310)                  

This message is likely due to the fact that Package Manager does non provide an interactive final or dialog where you tin enter your username and password for HTTP, or your passphrase to unlock your SSH central:

• With HTTP(S), every time you lot log onto BitBucket, GitHub or GitLab you need to enter your username and password in a terminal or a dialog box. However, the Parcel Manager does not provide an interactive terminal or dialog where you lot tin can enter your username and password for HTTP(South).

  To bypass this, use one of the workarounds suggested in Solutions for HTTPS.

• SSH uses a pair of public and private SSH keys. Yous can add your public SSH cardinal to Bitbucket, GitHub or GitLab and then access repositories without having to enter a username and password.

  However, if you lot accept set up a passphrase to go on your SSH central condom, you notwithstanding have to enter that passphrase in a terminal or a dialog box in order to authorize your key. In that example, you lot can use an SSH agent that can unlock your SSH central to authenticate with the Package Manager on your behalf.

Solutions for HTTPS

The Package Manager does not provide an interactive last or dialog where you can enter your HTTP(S) username and password. To bypass this, apply one of these workarounds:

• Utilize a credential managing director (Git Credential Manager for Windows or OSXKeyChain). Credential managers handle sending the countersign without having to utilize a terminal or a command prompt.
• Use git-credentials from a terminal or control prompt. Then launch the Hub from the same concluding so that Unity has access to the cached or stored credentials.
• Use SSH to authenticate instead. If you set up your SSH fundamental without a passphrase, the Package Manager doesn't take to decrypt it in guild to authenticate with the Git server. If you lot decide to use a passphrase for added security, you can all the same get around the authentication problem by using the ssh-agent on either macOS or Windows.

Solutions for SSH

If you are using the SSH protocol to install a parcel by Git URL, y'all might get an authentication error from Git. This typically happens when you lot gear up up a private SSH key on your local machine that is protected by a passphrase.

The solution to this problem is to fix upward an SSH agent that can unlock your SSH central to cosign with the Package Managing director on your behalf. Follow the instructions in the section that corresponds to your operating organization:

• Setting up OpenSSH for Windows
• Calculation SSH keys to your SSH Agent for macOS

Setting upwards OpenSSH for Windows

The native Windows OpenSSH version of the ssh-agent works better than the version available by default with Git for Windows. This procedure explains how to set up the OpenSSH client and add together your primal to its ssh-amanuensis. If you are using Git for Windows, you lot tin as well prioritize the native Windows OpenSSH over the Git for Windows SSH agent:

1. Make certain the OpenSSH Client is installed by searching for it in the Windows Settings Optional features window (Offset > Settings, then search for "Optional features"). This applies to Windows 10+.

2. Cheque your %PATH% surround variable to make sure the native Windows OpenSSH location appears (for example, C:\WINDOWS\System32\OpenSSH\).

   Note: If you are already using Git for Windows, make sure the native Windows OpenSSH location appears before the Git for Windows SSH location in your %PATH% variable. This ensures that Windows uses the native Windows OpenSSH agent over the Git for Windows SSH agent.

3. In a PowerShell terminal, start the ssh-agent process and make sure it starts automatically:

                 # Fix the ssh-agent service to start automatically and manually start information technology now Get-Service ssh-agent | Gear up-Service -StartupType Automatic # Run the ssh-agent process to commencement the ssh-amanuensis service ssh-agent                          

4. Import your primal into the ssh-agent by running ssh-add together on the command line and and then post-obit the instructions. By default, the amanuensis adds the %USERPROFILE%\.ssh\id_rsa key and prompts you for the password.

                 # Import the key ssh-add                          

   To use a different cardinal, you tin specify information technology as an argument:

                 # Set the ssh-agent service to start automatically and manually start it now ssh-add <your-secure-ssh-key-proper noun>                          

   If you lot can't remember the name of your key, y'all tin can ask the amanuensis to list them:

                 ssh-add -l                          

5. If you lot installed Git for Windows, reset the %GIT-SSH% environment variable to make certain that Git ever uses the native Windows OpenSSH version of the ssh-agent:

                 [Environment]::SetEnvironmentVariable("GIT_SSH", "$((Become-Control ssh).Source)", [System.EnvironmentVariableTarget]::User)                          

Adding SSH keys to your SSH Amanuensis for macOS

Use the following command to add your SSH keys to the ssh-agent running on your macOS system:

          ssh-add -K ~/.ssh/<your-secure-ssh-key-name>                  

After you run this command, the terminal asks for the password to unlock your SSH cardinal and then adds it to the macOS keychain. Nevertheless, one time you restart your arrangement, every cardinal stored in the ssh-agent is reset.

To forbid re-entering your password subsequently restarting your arrangement, open the ~/.ssh/config file (or create 1 if you don't find information technology), and add the following:

          Host *     UseKeychain yes     AddKeysToAgent aye     IdentityFile ~/.ssh/<your-secure-ssh-fundamental-name>                  

Restart your machine to utilize these changes.

Tin't update Git version

If you are trying to update your Git dependency The Parcel Manager retrieves Git dependencies from a Git repository directly rather than from a package registry. Git dependencies use a Git URL reference instead of a version, and at that place's no guarantee well-nigh the package quality, stability, validity, or even whether the version stated in its package.json file respects Semantic Versioning rules with regards to officially published releases of this package. More info
Run into in Glossary to a newer version from the repository, but it's not working, information technology's probably because your Git dependency is locked. If you lot want to update your Git dependency to a newer version from the repository, utilise the Add packet from git URL button and enter a Git URL. For more information, see Locked Git dependencies.

'Failed to parse Http response' in My Avails context

If you see the post-obit message in the Console window when trying to download an Nugget Store package, there might exist a problem with your Asset Shop enshroud:

[PackageManager] Error Failed to parse response. UnityEditor.AsyncHTTPClient![:D](https://forum.unity.com/styles/default/xenforo/clear.png)one(Land, Int32)

To solve this trouble, delete all downloaded avails from the Asset Store package directory and then endeavor downloading the assets again.

Warning: If your projection contains a lot of nugget data, this might take a lot of fourth dimension and bandwidth to re-download everything.

Missing 'My Registries' in the Parcel Manager window

Not all registry providers are compatible with Unity'south Package Manager. If the package registry server you added does not implement the /-/v1/search or /-/all endpoints, your scoped registry is non compatible with Unity'south Bundle Manager, and doesn't appear in the My Registries context in the Parcel Director window.

Missing MonoBehaviour errors

While edifice, if there are a lot of errors virtually Missing Behavior, the UnityLinker might be mistakenly stripping out a component that information technology thinks is unreferenced. It oftentimes does this considering the stripping level is also ambitious. For example, if you have a prefab An asset blazon that allows yous to store a GameObject complete with components and backdrop. The prefab acts as a template from which you lot tin can create new object instances in the scene. More info
See in Glossary in an AssetBundle that references the SpriteShape component in the 2nd SpriteShape parcel, the object might be missing and might generate compiler warnings.

To fix this, you tin either lower the stripping level for the UnityLinker or declare the package'due south assemblies within the link.xml file in order to preserve them from existence stripped:

          <linker>     <assembly fullname="Unity.second.SpriteShape.Runtime" preserve="all"/>     <assembly fullname="Unity.2nd.Mutual.Runtime" preserve="all"/>  </linker>                  

For more than data on stripping levels and the UnityLinker, see Managed code stripping.

Loading error for hostfxr.dll on Windows

If the Panel reports that the hostfxr.dll library was constitute, but Unity failed to load it from C:\<path_to_app>\hostfxr.dll, y'all can fix this fault on Windows 7 or Windows Server 2008 R2 past installing both KB2999226 and KB2533623 patches.
