[SOLVED] qt5 update break

Hey guys, I'm back. Qt5 seems to have broken, I'm getting errors from trying to open VLC & Barrier.
Code: [Select]
Cannot mix incompatible Qt library (5.15.3) with this library (5.15.4)
Aborted

I removed qt5-styleplugins and now it works. So I guess that package needs to be updated? Let me know when its safe to update!

I had the same problem. After a few hours I did pacman -Syu again and the new version was downgraded to 5.15.3 again and everything worked. I guess 5.15.4 was removed for some reason.
But now I have another problem. 5.15.4 is back again but when I do pacman -Syu I have an "invalid signature" error. Not sure if it is related to the previous problem.
Edit: so now the invalid signature error disappears and I've sucessfully upgraded. Qt apps are working fine.

same here, sddm starts, but blank screen
this happens after a bunch of qt5-xxx packages were updated to 5.15.4 today.
solution: downgrade to 5.15.3 these packages
exemple:
Code: [Select]
pacman -U /var/cache/pacman/pkg/qt5-base-5.15.3xxx
After that, my GUI is back again ;)

For now, X being sensitive to qt5,i added in /etc/pacman.conf
Code: [Select]
IgnorePackage = qt5-*
So they wont be upgraded again

Hm, only downgrading qt5-base doesn't seem to work for me, because then the software complains about mixing libraries. And trying to downgrade all qt5 libraries through grobbing didn't do it either.

Well, that's kinda what I'm trying to do, but it refuses even when I run with nodeps.
