Package resolution error when using a Git dependency referencing an annotated tag in its Git URL

Packman

-

How to reproduce:
1. Open attached project "Archive.zip"
2. Open Package Manager window
3. Add a Git dependency to the package using the tag as revision ("git+file://(absolute/path/to/pkg)#v1.0.0", for instance "git+file:///Users/maximeb/UnityProject/Archive/pkg#v1.0.0")

Expected result: The "pkg" package should be successfully added
Actual result: The package is not added to the project and an error is printed in the console:

Reproducible with - 2019.4.24f1,2020.3.2f1,2021.1.1f1,2021.2.0a9, 2021.2.0a14
Not reproducible with - 2019.4.23f1,2020.3.1f1,2021.1.0f1,2021.2.0a8

The error:
"An error occurred while resolving packages:
Project has invalid dependencies:
pkg: Error when executing git command. fatal: update_ref failed for ref 'HEAD': cannot update ref 'refs/heads/master': trying to write non-commit object 1701a603f21da447f378b943e707522dfd4d5ddc to branch 'refs/heads/master'"

    After making sure git is in the path, I still get the same issue.

    A re-import of the project may be required to fix the issue or a manual modification of D:/Seedling_Project/...../Packages/manifest.json file.

    My issues have been solved by now (see https://fogbugz.unity3d.com/default.asp?1336823_c0t2noqpvtu36lhr)

    Root of my issue was that I installed Git on Windows via scoop. And the way scoop handles the link to the Git executable was messing with Unity.

    Solution: put the full path to your Git executable as one of the first entries on your PATH env variable.

    > it DOESN'T work on 2021.1.5. it is still broken!

    I can confirm this. Still broken with the same error message.
    Just downloaded 2021.1.5f1 and tried it with an URL from GitHub.

    Confirmed that it work on 2021.1.0 but not in 2021.1.1.
    Also, it DOESN'T work on 2021.1.5. it is still broken!

    Trying to install a package from github (e.g.: https://github.com/org/repo.git) throws this error in the console

    [Package Manager Window] Cannot perform upm operation: Unable to add package [https://github.com/org/repo.git]:
    Could not clone [https://github.com/org/repo.git]. Revision [HEAD] could not be found. [NotFound].

    I'm experiencing the same issue as achimmihca, but with 2019.4.24f1; we have an URL like so:

    ```
    ssh://git@gitlab.com/company/repo.git#1.0.2
    ```

    And Unity keeps complaining that this tag does not exist (it does). Using a commit hash doesn't work either, nor does simply not specifying anything using the "#" symbol (then it just complains that "HEAD" cannot be found).

    I've reverted back to Unity 2019.4.18f1, where this works fine, so it must have been broken in a version in between.

    In 2021.1.1f1, I have the issue always when I use the "path" parameter.
    I also tried the suggested workaround, but even with commit ID, branch name or tag name (e.g. "https://github.com/my-user/my-repo.git?path=foo/bar#revision") the issue occurs.

    Thus, the suggested workaround does not seem to work in all cases.
