A PR is available to cope with this issue. I'm still testing it over the chaoss repos (kibiter excluded)

[inishchith]

@valeriocos Thanks for working on this. Do you want me to test the fix?
( if you know how to reproduce it please let me know )

[valeriocos]

You're welcome! Yes, feel free to test it. It's pretty difficult to replicate because it doesn't appear so often. I tried with graal and the error didn't appear, then I tried with a battery of repos (the chaoss ones) and it popped up.

I also encountered a similar error. Execute command:
graal cocom 'my_repo'--worktree-path /tmp/cocom --branches release-dev > graal-cocom.test
I got a error Line count, exceeded timeout: /tmp/cabc/.../lib/lambda-stack.ts
Execute command graal cocom 'my_repo'--worktree-path /tmp/cocom --branches release-dev > graal-cocom.test again and error Impossible to checkout the worktree occur
