After the last pamac update, I’m getting some strange behaviour between pamac and polkit1 in KDE. Even with a wrong password, pamac can install/remove/update packages when executed via the terminal. GUI doesn’t allow it without a valid password being entered. All is well with it in /etc/passwd
I just tried pamac upgrade used the wrong password and got the same message as you.I tried it again with the right password and it showed I needed updates.
driver / module was not loaded (probably r8169), you can try manually (# modprobe r8169 and watch journalctl) but the question remains why it didn’t on startup.
Same controller / kernel here, all is fine.
Found the issue! I missed an error on pamac stating “bad return status for module build on kernel: 6.2.6-1-MANJARO”. So I rebuild r8168-dkms and everything is back on track. Thanks, @dragan, for checking, it saved me some debugging.
