I always got the message
gitlab-ce is already the newest version (11.2.3-ce.0).
so I found out, that my package sources were outdated. To solve this you have to update the package list by executing a predefined script from the official Gitlab package site. If your installation is based on the community edition follow the “quick install instructions” from
gitlab/gitlab-ce – Packages · packages.gitlab.com
otherwise from
gitlab/gitlab-ee – Packages · packages.gitlab.com
After successfully executing the script take a look by
apt list –upgradeable
if there is any new version found. If yes, be shure that your setup won’t be broken on upgrade and follow the recommended upgrade list from
apt list gitlab-ce -a
to list all available gitlab packages.
Then execute the following command
apt upgrade gitlab-ce=14.0.0-ce.0
