I upgraded a whole bunch of packages today but it resulted in MATE breaking down. The GUI around windows do not appear, the panel does not show any currently running programs, nothing can be minimised/maximised or switched; overall an almost unusable mess.
I am just posting so that admins/moderators can take required action (perhaps an announcement to be careful?).
For anyone who upgraded and is looking to get their system to working state, fastest way is to follow the Arch Wiki to edit your pacman mirrorlist (MAKE A BACKUP JUST IN CASE!) to an archive version and force downgrade. While this downgrades other packages, the new update (as of today) had 60 packages so it will be really long to downgrade one at a time.
pacman -Syyuu and a restart later things should normal again.
@developers , is this a MATE specific issue? Should this be reported upstream to MATE devs?
Edit: Forgot to add the pacman log. Here is my log during the upgrade:
There were a lot of packages and I am currently unable to locate which packages are responsible for the breakage. I will try a bit later to see if there is a specific package causing the issue.
