Authentication failed when typing the password for the first time in Pamac/Manjaro Settings Manager

[AltheaRamnar]

Hi!

After the latest update I seem to be having some troble when authenticating via GUIs in KDE. The password works fine in terminal-based apps but always fails when typing it for the first time in e.g. Pamac or Kernel updater in Manjaro Settings Manager. It works, however, when I type it for the second time.

Polkit looks like this:

I checked and rechecked - I always type it correctly, but the first attempt after opening an application always fails. The second attempt always works.

Really strange. I’ll have to check on mine, but try adding a few characters then deleting and adding your correct password just in case the field isn’t completely clear … and see if using the GUI “OK” rather than hitting Enter makes any difference? … at least one application on my system wouldn’t take the password with the latter. (It’s good practice, anyway, IMHO).

I don’t suppose a copy & paste worked, if you tried that?

it’s this bug - polkit-kde-agent crashes with nullptr (only for some pc), fixed in 6.0.5 in testing branch

Workaround ?
before use polkit, run /usr/lib/polkit-kde-authentication-agent-1 &
