Install updates from Discover without password ?

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

Sorry I thought that Discover was only used on KDE neon, which thefore is the distro, and the CLI equivalent is indeed the one you mentioned.

So what's the solution for this distro ?

Thanks
- 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.

Yes, and many distros have a polkit rule set up to allow installing or updating without a password. You can likely just copy it from Fedora or sth

Could you please elaborate on that ? Thanks
- Fedora just has
  
  polkit.addRule(function(action, subject) { if ((action.id == "org.freedesktop.packagekit.package-install" || action.id == "org.freedesktop.packagekit.package-remove") && subject.active == true && subject.local == true && subject.isInGroup("wheel")) { return polkit.Result.YES; } });
  
  in /usr/share/polkit-1/rules.d/org.freedesktop.packagekit.rules. If you put the same file in there, it should work.

Flatpacks usually don't require password

Yes but APT packages are the ones requiring the password. Thanks

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

Many Distros use polkit instead of sudo actions. Though many sudo actions dont have polkit rules.
