KIO library error (

executing KDE applications from xfce (eg. okular, probability all the application) I got the following error:

symbol lookup error: /usr/lib/ undefined symbol: _ZN4KJob14percentChangedEPS_mNS_14QPrivateSignalE

the installed kio is

extra/kio 5.82.0-1 (kf5)

I fix the problem by downgrading KIO

sudo pacman -U kio-5.79.0-1-x86_64.pkg.tar.zst

loading packages...
warning: downgrading package kio (5.82.0-1 => 5.79.0-1)

looking for conflicting packages...

Please write me if you need more information.

Please resolve the bug for the next upgrades.


Sounds like you might have a mismatch of -git and non-git frameworks packages.

Can you provide the output of pacman -Qs git please.

pacman -Qs git
