checkout@v4: remote: git: 'lariat' is not a git command

[leongross]

In the u-root project we use (presumably) the latest version of checkout@v4 in our CI. The CI failed once with the following error:

 remote: git: 'lariat' is not a git command. See 'git --help'.        
  remote: aborting due to possible repository corruption on the remote side.
  Error: fatal: protocol error: bad pack header
  The process '/usr/bin/git' failed with exit code 128
  Waiting 13 seconds before trying again

After re-running the ci (more precisely git commit --amend --no-edit && git push -f)

I came here because I'm getting the exact same error in a workflow that's triggered by a cron schedule. The run that ran 1 hour earlier was successful using the same git fetch command and sha. Could this be on GitHub's server side?

Appears to be a symptom of this incident: https://www.githubstatus.com/incidents/q3xqwmcxzkqq

The issue seems to be resolved, but it seems as if there was some race condition that should be fixed, so I keep this issue open.
