Error switching branch: failed to fetch

[Freshwood]

Actually the git plugin can not re checkout a remote branch
Steps to reproduce:

• Create a repository to with an additional remote branch e.g. remotes/origin/test
• Then checkout the remote/origin/test branch
• The checkout is successful. A new local branch with name 'test' is in the list.
• Later on when the user click again on the remotes/origin/test branch then the following error is shown:

Error switching branch
Failed to fetch

Please, find attached the STR as GIF:

Desired behavior:

• The plugin re checkout the remote branch and will overwrite (Display dialog box?) the local branch
  OR
• The plugin will block the checkout of an already checked out remote branch.

Hi @Freshwood I think this may be due to the slashes in the branch name ref: #686

Can you try installing the latest release candidate and see if the issue persists:

pip install jupyterlab-git==0.21.0rc0

Hello @ianhi,

thank you for your reply.
I looked at the code.
The error will be raised in the following line:

jupyterlab-git/jupyterlab_git/git.py

Line 760 in bf58cec

cmd = ["git", "checkout", "--track", branchname]

The first try will always work. When you retry to checkout the remote branch (with tracking --track) then you will get an exception. (This is a normal git behavior)

Many thanks

Freshwood
