Without telling your distro this question is not helpful.
Discover uses packagekit, an abstraction layer that can do things like install, update, remove on many different distros.
So this might be distro-independent, but maybe not.
Try to enter in the terminal pkcon upgrade and if a GUI password prompt pops up, click on "expand" and see the action that is used like org.somenama.packagekit_update
This GUI prompt might also already be the one you described
I used Neon for a while. Again, can you please give the needed information. If the password dialog shows, at the left click on "expand"/"show more" and you see the exact action that is executed.
Then have a look at the rules in my linked repo, and replace the action in "libvirt" with that, and the group with "wheel"
(Use groups and send me the output, no idea if the sudo users are in the sudo group on Ubuntu)
Then send that rule, embed it in
```
Rule
```
To format correctly. I look at it and if it is correct, we go on.
For flathub packages, you could switch to user installs instead of system. Settings, then click the up arrow next to flathub (user) (if it's configured, otherwise you'd have to add it)
It will prevent multiple users from being able to use the same installation of packages, but if you're the only user if the machine it doesn't really matter
Yes but the only way I know is to make your whole system use no password
Do sudo visudo and change the line
%wheel ALL=(ALL:ALL) ALL
To
%wheel ALL=(ALL:ALL) NOPASSWD: ALL
and make sure you are in the wheel group you can check by doing groups | rg wheel
If not add yourself via
sudo passwd --add $USER wheel
Then edit the file ~/.config/kdesurc to be
[super-user-command]
super-user-command=sudo
This is a massive security risk but hey windows let's you do admin stuff without a password as well
