ppa-purge ppa:gnome3-team/gnome3-staging on Ubuntu 14.04 was very unreliable for me and left all sorts of outdated packages around, despite also removing large chunks of ubuntu-gnome-desktop. I had to manually downgrade mutter-common evolution-common before I could apt-get install ubuntu-gnome-desktop back. apt-show-versions | grep -v uptodate is a very handy tool for resolving situations like this. I was also surprised to discover that ppa-purge downgraded some packages to the version in trusty, while there was a newer version in trusty-updates. I had to apt-get upgrade after running ppa-purge to reduce the noise in 'apt-show-versions | grep -v uptodate'. Marius Gedminas -- One picture is worth 128K words.
