I’m doing the following
pc051:~ # zypper in -t pattern xfce
Reading installed packages...
'xfce' is already installed.
Nothing to do.
pc051:~ # zypper rm -t pattern xfce
Reading installed packages...
'xfce' is not installed.
Nothing to do.
Previously I have successfully installed the pattern xfce with
zypper in -t pattern xfce
and as far as I can see in the manual page for zypper, removing a pattern should be just as possible as installing it.
What am I missing here? :\
