I'm sure that I saw a thread on how to do this in the past, however I couldn't find it. I am wanting to try the new desktop (which I know is in Maya), however since Lisa has no outstanding problems with functionality on my laptop I figured I shouldn't fix something that isn't broken.
I tried adding the Ubuntu repos as suggested at Linux Mint Installation Instructions
(the following is my /etc/apt/preferences
Pin: release o=linuxmint
Pin: origin packages.linuxmint.com
Pin: release o=Ubuntu
Pin: origin packages.mate-desktop.org
however when I do
sudo apt-get install mate-desktop
it still seems to fetch the older version. Is this file read by apt in any certain order, is there anything I need to change?
