Gitlab-ce Installation on Ubuntu 18.04 fails with message on database migration

I am installing GitLab CE on Ubuntu 18.04 using instructions here: https://about.gitlab.com/install/#ubuntu

It fails as shown below:

Running handlers:
There was an error running gitlab-ctl reconfigure:

bash[migrate gitlab-rails database] (gitlab::database_migrations line 54) had an error: Mixlib::ShellOut::ShellCommandFailed: Expected process to exit with [0], but received '1'

Your current database version is too old to be migrated. You should upgrade to GitLab 11.11.0 before moving to this version. Please see https://docs.gitlab.com/ee/policy/maintenance.html#upgrade-recommendations

Most services are down as a result. Therefore, I started it again with sudo gitlab-ctl start. It seems all is up:

However, when I try to access the URL in browser, the request times out with a 502. Please help me get around this issue.

Hi @chainhead, did you resolve this problem? I have too :frowning:
