Description Xuo 2017-01-10 18:32:25 CET

Description of problem:

Hi,

I can't run mcc from the desktop icon nor as user xuo.
This bug looks more or less like this one (https://bugs.mageia.org/show_bug.cgi?id=16396).
It occurs for me on at least 2 laptops.
I am running mageia5 x86_64 on the first one, mageia5 i686 on the second one.

It does not depend on the fact that I log in or out from a previous session. This behaviour occurs since several months but I was leaving with it (see (in french) https://www.mageialinux-online.org/forum/topic-20672+drakconf-mcc-ne-se-lance-pas-a-partir-de-son-icone-sous-xfce.php). As I've installed Mageia on another laptop, and see this bug is still there, I open this bug.

As you can notice below, my user id is less than 1000 (500).


/home/xuo 16 # mcc

Hi,

I could make it work.
I had to remove the directory .config/autostart that contained the following files :
-rw-r--r-- 1 xuo users 208 aoÃ»t 9 2015 CryptKeeper.desktop
-rw-r--r-- 1 xuo users 29 sept. 29 21:28 deja-dup-monitor.desktop
-rw-r--r-- 1 xuo users 29 aoÃ»t 9 2015 mageiawelcome.desktop
-rw-r--r-- 1 xuo users 214 sept. 27 20:49 Nextcloud.desktop
-rw-r--r-- 1 xuo users 237 sept. 29 21:10 NextCloud.desktop
-rw-r--r-- 1 xuo users 212 sept. 27 20:44 ownCloud.desktop
-rw-r--r-- 1 xuo users 29 juil. 11 2015 polkit-mate-authentication-agent-1.desktop

From now, running 'mcc' as another user than root opens a dialog box where I can enter the root password and the mcc icon or the mageia-update one work too.

Regards.

Xuo.

Hi,

I consider this bug as "resolved" even though I didn't understand the reason why these files could prevent from running the mcc command or the corresponding icons.

Regards.

Xuo.

That's not a proper fix.
There's still an issue with mate-polkit
What desktop are you using?
What's the result of the following command?
rpm -q --whatprovides polkit-agent

Hi,

I am using xfce with mageia 5.
# rpm -q --whatprovides polkit-agent
mate-polkit-1.8.0-6.mga5

Comment 5 Marja Van Waes 2018-07-12 13:45:13 CEST

Hi Eric/Xuo,

Did this bug get fixed? If so, please change its status to RESOLVED - FIXED

If it didn't, then we regret that we weren't able to fix it in Mageia 5. Mageia 5 has officially reached its End of Life on December 31st, 2017 https://blog.mageia.org/en/2017/11/07/mageia-5-eol-postponed/
It only continued to get important security updates since then, because we were waiting for the big Plasma5 update in Mageia 6, that fixed many of the Mageia 5 => 6 upgrade issues.

If you haven't seen that this bug got fixed, then please check whether this bug still exists in Mageia 6. If it does, then please change the Version (near the top, at the left) to "6". If you know it exists in Cauldron, then change Version to Cauldron. If you see it in both Cauldron and Mageia 6, then please set Version to Cauldron and add MGA6TOO on the Whiteboard.

Hi,

This bug does not occur on Mageia6. I consider it as solved.

Xuo.
