Bad revision fatal error when .git is a symbolic link with symbolic links inside #5426
Description
Describe the bug
I'm migrating Android repo tree from Gerrit to GitHub and I need to convert some repositories to LFS due to the file size limit. Android uses the repo tool for repository management, which uses symbolic links for .git and directories inside .git for a given repo.
For example .git points to ../../../../../.repo/projects/xyz/core.git/ and inside of it:

-rw-r--r-- 1 docker docker 176 Jul 13 21:30 FETCH_HEAD

When trying to perform any git lfs migrate operation, it fails with:
$ git lfs migrate info --skip-fetch
Error in git rev-list --reverse --topo-order --do-walk --stdin --: exit status 128 fatal: bad revision 'refs/heads/upstream'Once I copy the .git with cp -rL git-lfs works as expected.
To Reproduce
Steps to reproduce the behavior:
- Clone a repository, e.g., with the
repotool, so that.gitis a relative symlink and all directories inside are relative symlinks. - Try to run
git lfs migrate info --skip-fetch
Expected behavior
Migrate tool works.
