I have an Ubuntu GNOME 16.04 with GNOME 3.18 64-bit VM, and in that VM I needed to test something in the
xenial-proposed channel so I activated it in the
sudo apt-get update && sudo apt-get dist-upgrade and installed all the upgrades from the
xenial-proposed channel as I couldn't find a way to get it just to upgrade the package I needed.
Now however I wish to downgrade all the packaged upgraded to their
xenial-proposed versions to their version in the stable/normal channels, but how can this be achieved? Can I use
ppa-purge to do this? And if so, how?
If I just disable the
xenial-proposed channel via the same means that I enabled it will the packaged installed and upgraded to their
xenial-proposed versions start to receive updates again from the stable/normal channels once the version numbers there are higher than the installed or will I receive no updates at all then until I enable the
xenial-proposed channel again?
