Hello. I have ubuntu deb installation and I don’t know upgrade path. When I upgraded from 13 to 15 it was clear in documentation, but now it’s not clear at all. For example 15.1.0 > 15.3.2 and so on. Or can I upgrade to the latest straightaway?
Take a look here: Upgrading GitLab | GitLab
From 15.1.0 you need to upgrade via 15.1.6, 15.4.6 and then to latest 15.x release. Obviously wait for all background migrations to finish before starting next upgrade.
