I was asked on the Debian forum whether the Jessie version of 1.18 in the OBS would work with Stretch. In a Live session of antiX 17 alpha, I installed the mate-desktop-environment metapackage from Stretch to pull in MATE, then removed the metapackage. I then did a full update, installed aptitude, added my OBS repo, and did
It upgraded everything, except it had to remove the MATE "marco" window manager, since it depended on a libgtop2-7 only found in Jessie. However, when I then logged out and then back into a MATE session, apparently it fell back onto one of the other window managers that came with antiX, and MATE seemed to look and work fine in a brief run-through. I suppose the marco packages could also just be rebuilt from the debianized source on the users own Stretch machine if they really wanted to get it up with the rest of MATE.
