Context: We're trying to migrate our gitlab server from one provider to another and upgrade it to the latest release and we're trying to find a way to do it in a way that doesn't break everything.
I have a VPS with a gitlab version 7.0.0 (omnibus) on an ubuntu OS which I'm trying to upgrade to the latest release. Apparently, gitlab didn't have a package repo at the time when 7.0.0 was a thing so I followed this page to try and upgrade via repo. To be safe, I started another VPS instance on the new provider, made a backup through this, copied the deb package from the original server, installed the deb package and did a restore which worked perfectly. Accessing the new VPS by IP works just as well as the original.
Then I finally did the update as per instructions.
What I get instead by the end is this:
Chef Client failed. 9 resources updated in 21 seconds dpkg: error processing package gitlab-ce (--install): subprocess installed post-installation script returned error exit status 1 Errors were encountered while processing: gitlab-ce
I tried accessing via IP and lo and behold it broke with an error 500.
I tried digging through the details and I found this:
Error executing action `run` on resource 'bash[migrate gitlab-rails database]'
With my boss' blessing, and to rule out an environment issue, I tried making a snapshot of the gitlab server, started another VPS instance on the original provider and loaded it up with the snapshot, effectively cloning the server. I attempted the update on that and it still breaks. I tried manually downloading the package and installing via
dpkg which still doesn't work.
By this point, I'm not sure what I'm overlooking.
