Hi Andreas, I wonder why you get this error, because apt-get says it does not even know this package. If I like to remove a package that's in the database I get this output
veedel[~]# apt-get purge moon-buggy Reading package lists... Done Building dependency tree Reading state information... Done Package 'moon-buggy' is not installed, so not removed 0 upgraded, 0 newly installed, 0 to remove and 16 not upgraded. Maybe you may have removed some sources.list entries, so apt-get complains about unknown packages. > 2. fai-mirror complains that it doesn't know how to deal with "PACKAGES > remove". It doesn't include these packages either, so it is harmless but > may be easily correctable. This may be a bug of fai-mirror. You cloud also remove a package by appending a minus (-) to the package name but still let in in a PACKAGES install section. -- regards Thomas
