I’m on Testing branch, and can confirm that I also have libgtk-3.so.0.2411.32 on my up-to-date system. There was a recent downgrade of gtk pushed through on the Testing repos:
The OP might want to see if downgrading to the version of gtk3 (and some other packages that were also downgraded such as fakeroot) in the repos fixes the issue:
note the r, returns repos.
And thats what I usually ask for.
The other common one that is slightly more comprehensive is inxi -zv8.
It may be worth noting the differences between Farz and zv8 are mostly negligible differences in reporting extra memory info, processor flags, chroma color info, USB and volume information (including UUIDs), and top running processes (top 5 of each cpu and ram).
inxi -Fz was a user invention for whatever reason.
There should have also been no reason to use -Syyuu which would unnecessarily force resync and hammer the server. -Syuu should have sufficed to allow downgrades.
Also the ‘problem with xfce apps and packages rolled back’ is detailed in some other thread(s) that I dont care to go looking for just now.
