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?

Backup the file that is causing the errors and update the systems mime database:

sudo mv -vi /usr/share/mime/packages/kde.xml /usr/share/mime/packages/kde.xml.bak
sudo update-mime-database /usr/share/mime

This should fix the warnings.

This was discussed in Why does update-mime-database complain about uri/rtspt and other unusual types? It is caused by kde.xml and they have not fixed it yet. Here is a bug report.

Also it's uri/rtspu, not url/rtspu you should be grepping.

You should check /usr/share/mime/packages for the specific xml that contains the phrase you get .

For example, my problem was Unknown media type in type 'chemical/...... I found the file /usr/share/mime/packages/chemical-mime-data.xml.

Using cat on the file showed me that the package was the same chemical-mime-data V 0.94

So I ran:

sudo apt-get remove chemical-mime-data

The bug stems from KDE, and has not been fixed since 2008:
