Each time apt-get tries to process triggers for shared-mime-info, it reports warnings like:
...
Processing triggers for shared-mime-info...
Unknown media type in type 'all/all'
Unknown media type in type 'all/allfiles'
Unknown media type in type 'uri/mms'
Unknown media type in type 'uri/mmst'
Unknown media type in type 'uri/mmsu'
Unknown media type in type 'uri/pnm'
Unknown media type in type 'uri/rtspt'
Unknown media type in type 'uri/rtspu'
Unknown media type in type 'interface/x-winamp-skin'
I’ve checked /usr/share/mime-info but doesn’t see any of them:
/usr/share/mime-info$ grep 'url/rtspu' *
(Got nothing)
So, how to clean up my system so it won’t report these unknown media types?
sudo rm /usr/share/mime/packages/kde.xml
sudo update-mime-database /usr/share/mime
Should fix the warnings.
