I've seen this before and I was always able to fix it either by restarting polkit or just rebooting. Those solutions aren't working any more.

What's happening is that I am opening MCC, either by the icon on the taskbar or by typing "mcc" in a konsole window (as root or as user), I'm challenged for a password as is appropriate, then the Control Center splash screen appears. It then simply disappears. Starting it in a konsole shows me this:

And it just sits there - no control center gui appears. I also have to "reset" my konsole window for it to display input after that.

What is the best way to approach this? As I said, restarting polkit and rebooting haven't done the job. What's next?

Thank.

polkit restart or reboot doesn't help at all when your perl installation is broken. Also you don't mention which Mageia release that is.

Okay, this is next to impossible. I'm into my desktop from my phone via ssh trying to cut and paste. It is really not working. I'll try to get the rest of it this evening.

But I do want to thank you for your time and attention.

Okay, I'm back. Don't ask - it's complicated.

There it is. Please have a look.

And thank you for your time and attention in this. I do appreciate it.

Can you please post the output as root of

Code: Select all

rpm -V perl-base perl-Gtk2-WebKit

As root, that command returns nothing.

I attempted to install perl-base and perl-Gtk2-webkit and they both show that they are installed.

I'm at work now but will have direct access tonight when I get home.

Thanks again. I appreciate it.

That should be

Code: Select all

rpm -V perl-base perl-Gtk2-webkit

and it can be run as a regular user,

Code: Select all

[root@spike madams]# rpm -V perl-base perl-Gtk2-w
package perl-Gtk2-webkit is not installed

Tried to install it. No such package.

Again, still at work and doing this on my phone. Difficult user experience.

The Doktor's command was correct, my mistake.
Any output with the -V --verify switch indicates a problem.
You'll have to wait for the good Doktor to see where he's going with this.

Quick check before work:

Yes, the verification can be run as a regular user, but then rpm can obviously only verify the files it has read access to - so usually this needs to be run as root to check all files in a given package.
The verification checks the actual files against the checksums rpm stores internally, but also owner/group/permissions/modification time/size and so on and will output any deviation between what the rpm should contain vs. the actual files on disk.
For more details see http://www.rpm.org/max-rpm/ch-rpm-verify.html and http://www.rpm.org/max-rpm/s1-rpm-verify-output.html

@mark9117:
No output means all files should be OK, so those two packages shouldn't be the cause.

For the other output you posted, urpmq will only check the name given against the repos. If you only call urpmi with a package name, then it will simply tell you it's already installed.
To reinstall any given package which is already installed, use

Code: Select all

urpmi --replacepkgs --replacefiles packagename

Do you maybe have pipelight installed`?

I seem to be having a very similar problem, starting some time not long (a few days?) before 30th April.

mcc fails to start if invoked via the KDE menu. If invoked as a non-root user on command line from Konsole, it just sits there doing nothing until I hit CtrlC. If invoked from a non-GUI sessions (again non-root user), I get prompted for the root password, after which I am told

Code: Select all

polkit-agent-helper-1: error response to PolicyKit daemon: GDBus.Error:org.freedesktop.PolicyKit1.Error.Failed: No session for cookie
==== AUTHENTICATION FAILED ===
Error executing command as another user: Not authorized

If I invoke it as root from Konsole, all is well. Ditto for root from a non-GUI session -- getting the non-GUI version, of course.

And no, pipelight not installed.

Please start a separate thread for your issue, definitely not related to this, more of a polkit problem.

Nope. Pipelight is not installed.

# rpm -V pipelight
package pipelight is not installed


Sorry, so far got no further clues. Best report that as a bug, after searching if it hasn't been reported yet already: https://wiki.mageia.org/en/How_to_report_a_bug_properly
