E: Unable to find a source package for mate-user-share
From looking at a old bug from 2011 at bugs.launchpad.com/linuxmint , I found a reference to https://github.com/linuxmint/Mate-Packages/ and thought this is where I'd find source, but unfortunately that repo is no longer.
Where can I find the MATE source deb packages?
