Upgrade complete! If your GitLab server is misbehaving try running
  sudo gitlab-ctl restart
before anything else.
If you need to roll back to the previous version you can use the database
backup made during the upgrade (scroll up for the filename).

502 - Whoops, GitLab is taking too much time to respond.

i searched the logs, but can not find a error.

i removed the “unicorn” entries in config and added puma:

puma['worker_timeout'] = 60
puma['worker_processes'] = 2
puma['listen'] = ''
puma['port'] = 8090
puma['socket'] = '/var/opt/gitlab/gitlab-rails/sockets/gitlab.socket'
puma['pidfile'] = '/opt/gitlab/var/puma/'
puma['log_directory'] = "/var/log/gitlab/puma"
puma['per_worker_max_memory_mb'] = 500

i proxy gitlab on a own https nginx.

i use gitlab-ce since years, moved it to new debian buster, always found the update problems in the good docs.
But this time i have no idea where is the problem and where i can search.

what can i check to find the problem?

best regards,

i re-read update path.

looks i need first go to 12.10.6.

will test this…

now i wanted to go back to old version and recover update.

i first updated to 13.1.1 - and this already fixed my problem.

its back running :slight_smile:
