How to add Gitlab repository into ubuntu

Check status of all services gitlab
Run a update before list packages
Check all the available versions
apt list -a | grep gitlab-ce
Check version available for upgrade
apt list --upgradable | grep gitlab
Upgrade to specific version (my case 13.12.15)
apt install gitlab-ce=13.12.15-ce.0
