Sadly, when cloning a repository from Gerrit. the Gerrit’s commit-msg hook is not populated in the local repository git hooks folder.
Here’s a neat trick that I just learned that always puts that there.
scp -p -P 29418 <GERRIT_SERVER>:hooks/commit-msg ./
sudo mv ./commit-msg /usr/share/git-core/templates/hooks/
Hope you find it useful…
