Gitlab wont start (possibly due to upgrade): Cannot cd into /usr/share/gitlab, Failed to start LSB

Tried to visit the gitlab web interface but got Error 503. Tried systemctl restart gitlab.service and it reported back gitlab failed to start.
Journalctl -xe yields the following:

Sep 19 17:38:13 ##########-vm gitlab[27239]: /etc/init.d/gitlab: 59: cd: can’t cd to /usr/share/gitlab
Sep 19 17:38:13 ##########-vm gitlab[27239]: Failed to cd into /usr/share/gitlab, exiting!
Sep 19 17:38:13 ##########-vm systemd[1]: gitlab.service: Control process exited, code=exited status=1
Sep 19 17:38:13 ##########-vm systemd[1]: Failed to start LSB: GitLab git repository management.

I’ve checked and there is no /usr/share/gitlab folder in /usr/share. According to /varlog/apt/history.log there were two unattended updgrades this week but gitlab is not listed in either. I dont recall using apt to install gitlab, it might have been via url -LO https://packages.gitlab.com/install/repositories/gitlab/gitlab-ce/script.deb.sh
as I can see that in my cmd line history. Any help to recovery is welcome. Repository data seems to safe and I’ll do a back up of that now. Apologies if delayed in replying, we may be in a different timezone to the active community.

Apologies, was this the best place to post?
