Mate 1.8 has finally new Debian packages. Though it is partially in Debian sid but not all components.
If you are impatient then follow me here. One thing I will say. At the moment I would rather recommend to stay with the sid packages because the transition should be almost over and some bugs will come with an upgrade of the third party repository but nothing critical so I tried it just for you. :)
Remove the old Mate repo from your sources list, then add the new one:
Code: Select all
deb http://repo.mate-desktop.org/archive/1.8/debian/ jessie main
Code: Select all
apt-get update && apt-get install mate-desktop-environment-extra
Bugs I experienced: Mozo does not start and the shortcuts are still not fixed.
Have fun!
