Thanks for reporting the issue.

This is due to the new git owner check [1]. I suggested to skip the check as following:

# git config --global --add safe.directory /var/lib/zun/zun

Then, re-running your command should work. I submitted a patch to fix the installation guide [2].

[1] setup_git_directory(): add an owner check for the top-level directory · git/git@8959555 · GitHub
[2] Disable git owner check for zun (I5dd1e405) · Gerrit Code Review (opendev.org)
