Hi, thanks reporting this.

I think there is something missing with polkit with LXDE.

On my side, M8-Cauldron Plasma, user member of wheel group:

Running "mcc" from a CLI while under a X/Wayland session should open a GUI polkit-agent asking you for password.

Running "mcc" from a tty should ask you for password at prompt and should run ncurses version of MCC.

I also see this in cauldron, there with the default live user with no password.

Hi,

For Mageia 7, if you install task-lxde-minimal, you also need to manually install a polkit client (for LXDE, it is lxpolkit).  The simplest way to get a fully working LXDE session is to install task-lxde.

For Cauldron, I did not check using a live ISO but, I did not have any problem in a Virtualbox VM that was installed with a normal x86_64 ISO because it installed task-lxde and not only task-lxde-minimal.

Best regards,

Nico.

Hi Nico

Would it not be a good idea to have that dependency included in task-lxde-minimal instead of task-lxde?

Because in Mageia i.e MCC is a flagship component, and documentation - also for new users - expect it to just work to click it.

For using as fallback for another DE on a small device, full task-lxde is not wanted.

Have not tested in wayland

That could be a workaround, but do not work:

When logged in as user "live" in either the text terminal found at i.e Ctrl-Alt-F2 or using LXTerminal, i get the no sesson for coocie error as seen in comment #0.

task-lxde-8-3.mga8 move lxpolkit dependency from task-lxde to task-lxde-minimal

Verified fixed in Cauldron on a live persistent system install:
task-lxde-minimal update pulls in lxpolkit.
MCC is started both from icon and by entering "mcc" as live user in lxterminal, it dont ask for user password, probably as intended for live user.

Pinging this for mga7.

Suggested advisory:
========================

The updated packages fix a packaging issue:

lxpolkit should be a dependency of task-lxde-minimal rather than task-lxde otherwise, when installing only task-lxde-minimal, a polkit agent is missing to be able to launch Mageia Control Centre, for instance.

MGA7-64 LXDE on Peaq C1011
This notebook had no LXDE before, so just seeing the title on this bug, I installed task-lxde from MATE, logged out, logged in to LXDE: OK (of course).
Installed the new version of the two packages, and only then read about the original problem, which of course I couldn't replicate anymore.
Anyway, logged out, logged in again, and all seems OK. File types tested like odt, ods, odp, odb, internet access, access to NFS-shares.
Waiting for others to confirm.

Thank you Nicolas.
Yes Herman, at least you proved it did not get destroyed :)
I will try in a few hours mga7-32 on persistent USB stick.

Fixed, thanks :)

Repeated old experiment, using 32 bit Xfce persistent live:
1) Full normal update. Only desktop ever installed is default Xfce.
2) Lnstalled task-lxde-minimal, disabled autologin, reboot
3) Loged into lxde
4) Found MCC icon nonresponsive
5) Enabled updates testing and updated task-lxde-minimal, which pulled in lxpolkit 
6) Logged out and in again
7) MCC icon works
