Authentication dialog pops up and disappears at once

This happens when I run a program that asks for elevated privileges. Example:

  • In the pamac GUI tool when I press ‘APPLY’ in order to update or install some packages.
  • when I start partitionmanager and the program attempts to read the drives.

In both cases root acces is needed, so a dialog pops up with the title
‘authentication required’. I just have enough time to see this title and that it is a dialogbox which should allow me to enter a password, but then the dialogbox immediately closes, and teh calling program gives an error saying I am not authorized to perform the operation.

What can I do to make that dialogbox stay open so that I can fill out a password and click ok ?

There where similar issues brought up here in the last few weeks.
Typically after an update.
Some people had a problem, while the vast majority of others had none.

Look for these posts.
(I’d have to do this, too - in order to link to them :wink: )

One “solution” seemed to be to use a kernel >=linux612 if I remember correctly.
So that would be an easy one to try …

The dialogue box does stay open… there’s something else going on here… some extra information might help here (like the inxi output mentioned below).

It’s also possible for dialog boxes to disappear behind other windows.

One way to check this out:
Create a new USER and then try again with that USER. Then you can confidently say your SYSTEM is broken.

So anyway, welcome to the forum!

As a new forum user, please take some time to familiarise yourself with Forum requirements; in particular, the many ways to use the forum to your benefit:

The Update Announcements should be checked frequently for important update related information.

These announcements contain a Known Issues and Solutions section and should generally be checked before posting a request for support.

Meanwhile, posting some information could prove useful:

inxi -zv8 | grep -vE 'MAC|UUID|IP'

Also:

journalctl -p3 -xb --no-hostname

Could come up with something interesting…

Try to format (from the top icons when editing, click the PLUS icon and ‘hide’

I’ve had this problem in the past. In particular when I ran KDE’s partition manager and couldn’t work out why it was just sitting there doing nothing. My solution was to create a KDE rule which forced such dialogues to stay above all other windows.

I have noticed this in Ark, where the dialog with the entry box for the password for my encrypted backups is underneath the dialog with “wait for entry” animated something or other. I blamed the Nemo file manager I use, since it isn’t made for KDE. Perhaps I’ll try and switch kernel version around when I upgrade next time and see if anything changes.

Kernel 6.6 (LTS) or greater: :point_down:

Though kernels 6.12 (LTS) or 6.18 (LTS) are generally a better choice for most users, regardless.
