I look for a way to re-install the pattern mail_server including configuration files as if nothing was never installed.
I could not achieve this from yast gui.
I tried to remove the pattern, then delete the config files ( the files that i guess belonging to the pattern ) ; then re-installing the pattern give many errors when restarting because some files was missing (re-install was incomplete) in spamassassin.
I tried to download all the rpm files in a specific folder ( zypper in --download-only ) then install from the folder using
No need to move configuration files unless you want to save them (From the original post, that doesn’t seem to be the case).
When you do a “force re-install” you will over-write everything including configuration files.
When you do an update, you preserve configuration files.
