Dear Maintainer,

Precompiling assets...
Starting GitLab Unicorn
Starting GitLab Sidekiq
Could not find gem 'mysql2 (~> 0.3.16)' in any of the gem sources listed in your Gemfile or available on this machine.
Run `bundle install` to install missing gems.
The GitLab Workhorse is already running with pid 0, not restarting
..............................Waited 30s for the processes to write their pids, something probably went wrong.
invoke-rc.d: initscript gitlab, action "start" failed.
dpkg: error processing package gitlab (--configure):
