Github repo mirroring is failing with following error:

2:Fetching remote upstream failed: warning: unable to find all commit-graph files
warning: unable to find all commit-graph files
fatal: Unable to create '/var/opt/gitlab/git-data/repositories/@hashed/b0/c0/b0c01053daf84ec4dc166b6ba53a64bd3591373d74c88b37ba0eb2c491b533ca.git/./objects/info/commit-graphs/commit-graph-chain.lock': File exists.

Another git process seems to be running in this repository, e.g.
an editor opened by 'git commit'. Please make sure all processes
are terminated then try again. If it still fails, a git process
may have crashed in this repository earlier:
remove the file manually to continue.

I am having the same issue, any solutions for this?
