I been using OpenSuse, and all the way to Leap 15.2. I just been trying to upgrade form 15.2 to 15.3 and I realised it was uninstalling my mail server package
I am using CommuniGate, and the RPM is being uninstalled by 15.3 upgrade.
I tried to de select it from the "list of packages to be deleted’ and it was not possible.
Appreciate any advice.
