Fatal error from remote when pushing to alberti/ldap

When updating the key for jnewsome in #41022 (closed) I hit a similar issue as #41013 (closed) :

   3ce936a..d00c61c  master -> master

However, running the git config command did not fix the problem, likely because of the env -i bit unsetting $HOME and making git unable to find $HOME. I had to run make -C /srv/db.torproject.org/keyrings manually instead.

I'm wondering if the fix here is to change git pull with git -c safe.directory=/srv/db.torproject.org/keyrings/keyring pull in the Makefile?
