stderr: 'fatal: Unable to create '.git/index.lock': File exists.

I have a git script that fetches a file from a remote repository. Everything was working fine but then all of a sudden I'm running into this error below. Is their a way I can solve this using GitPython, any help will be much appreciated thanks.

GitCommandError
'git checkout origin/<branch_name> <filename>' returned exit code 128.
stderr: 'fatal: Unable to create '.git/index.lock': File exists.

if no other git process is currently running, this probably means a git process crashed in this repository earlier. Make sure no other git process is running and remove the file manually to continue.

It looks like the error is related to the git command-line tool, which might indeed have crashed, leaving a lock file preventing further access. This can possibly happen if the script is interrupted with Ctrl+C.

As there is nothing unusual about this happening, nor is there an indication that this is a bug in GitPython, I am closing this issue.
Please feel free to comment in the closed issue with follow-up questions or other comments that might make a bug reproducible.
