GitLab 7.5 -> 7.83 (Latest Version) Update Error

Hi GitLab,

I’ve recently upgraded from 7.5.3 using the upgrade instructions located here:

Sidekiq wont actually start after the upgrade – see below:

root@git:/home/git/gitlab# service gitlab restart
Shutting down Unicorn.
GitLab is not running.
Starting both the GitLab Unicorn and Sidekiq…Waited 30s for the processes to write their pids, something probably went wrong.

I can revert back to 7.5.3 from the backup created, however I just simply can’t upgrade as it keeps failing to start Sidekiq due to the above error.

Any advice or help would be greatly appreicated.
