Polkit is not working anymore

1

hey! i have tried to make polkit work and it worked for a time, and it is not working anymore IDK why. my nixos configuration -


  # Polkit
    systemd = {
    user.services.polkit-gnome-authentication-agent-1 = {
      description = "polkit-gnome-authentication-agent-1";
      wantedBy = [ "graphical-session.target" ];
      wants = [ "graphical-session.target" ];
      after = [ "graphical-session.target" ];
      serviceConfig = {
          Type = "simple";
          ExecStart = "${pkgs.polkit_gnome}/libexec/polkit-gnome-authentication-agent-1";
          Restart = "on-failure";
          RestartSec = 1;
          TimeoutStopSec = 10;
        };
    };
  };

also i do have polkit_gnome package installed on my nixos.

Is there a reason you aren’t using the nixos polkit module? Usually, any modules which need polkit will also enable this option or assert that the option should be set to true.

3

hmm, i’ve tried that with that module and without module, non of them worked for me. i do need graphical polkit such as gnome polkit, but i am unable to run it.

4

What does the status of the service show?

What errors do you get when an application tries to use the polkit gui?

7 
$ gparted
Error executing command as another user: No authentication agent found.

EDIT = seriously have a pain with polkit, need to fix this quickly but i can’t.

8

KDE, or mate polkit will be fine, just tell how to enable that?

9

You enable them by installing them and running them on login. Just pick one from Nixpkgs, add it to your config to install it.

10

That’s not the service for the graphical polkit that you shared. Run systemctl status polkit-gnome-authentication-agent-1

11 
$ systemctl status polkit-gnome-authentication-agent-1
Unit polkit-gnome-authentication-agent-1.service could not be found.
12

My bad, it should be systemctl status --user polkit-gnome-authentication-agent-1

The service is failing to run. Please post the output of journalctl -u polkit-gnome-authentication-agent-1, we’ll see if it explains why it is failing.

15

idk why it has no entries,

$ journalctl -u polkit-gnome-authentication-agent-1                                            
-- No entries --
16

Try running /nix/store/fq1igqqj97dsp0b7wallm70sfd5y3vyl-polkit-gnome-0.105/libexec/polkit-gnome-authentication-agent-1

17

this thing worked half, after running that form kitty, now i am getting that polkit pop up when i did gparted but i am getting a new error,

(polkit-gnome-authentication-agent-1:4700): polkit-gnome-1-WARNING **: 20:06:48.464: Unable to get a pixbuf for GTK_STOCK_DIALOG_AUTHENTICATION (gtk-dialog-authentication) at size 48
18

That is just a warning, it isn’t relevant. If you run systemctl restart --user polkit-gnome-authentication-agent-1 then systemctl status --user polkit-gnome-authentication-agent-1, does it still say failed?

19

it is not just a warning, gparted does not launch. and as you said when i do -

EDIT = still can’t launch gparted and it is a polkit issue,

Error executing command as another user: No authentication agent found.

It is just a warning, the output shows that it is a warning. These GTK warnings are common. The crash is being caused by something else. Can you share your entire configuration? I’ll test the polkit and see if I can get it running on my machine.
