[SOLVED] No access to MCC from GUI - polkit update to 0.113

[DiBosco]

pkexec whoami
root

I did have to enter my root password in the pop-up dialogue box

FWIW everything is taking AGES to start up. Even programs like kwrite and Dolphin are taking 20 or 30s to start!

So polkit is working just fine.

What is the output/result if you run as normal user in a terminal

Code: Select all

echo $DISPLAY
drakconf
pkexec /usr/libexec/drakconf
pkexec /usr/libexec/drakxconf

[DiBosco]

Code: Select all

drakconf
No protocol specified
Cannot be run in console mode.


Code: Select all

pkexec /usr/libexec/drakconf
No protocol specified
Cannot be run in console mode.


In both those cases it comes up with a GUI style password dialogue pop-up box asking for the root password which I enter.

if I run:

Code: Select all

pkexec /usr/libexec/drakxconf

It launches the password dialogue box asking for root password, I enter that and it opens up a text based program that calls itself Control Centre, list options such as 3D Desktop Effects, Auto install, Bootloader etc. I can go into those options and it brings up text submenus.

Your display env. variable is not set correctly, or something else is weird about your X server.

You also missed

Code: Select all

echo $DISPLAY


[DiBosco]

Ooops, apologies!

echo $DISPLAY
:0

I can't run the new packages GUI when it comes up with the white exclamation mark in the red circle either. Other things seem to work.

[DiBosco]

I have done the following:

strace -o no_work.txt drakconf

And attached the no_work file. It seems to be telling me there are loads of missing files in /usr/lib/perl5 and /usr/lib/libDrakX

They are, indeed, missing. I have nothing to compare it with at the moment as I'm away from the office, only working on this laptop, does this help point out where the problem lies? Are there packages that I've somehow lost?

I tried uninstalling and reinstalling drankconf, it then also installed drakgaurd, which didn't seem to be removed when I did urpme drakconf, but that didn't help.

Does the strace thing help?

[doktor5000]

Nope, doesn't help at all, strace will show all calls when some library is searched in all available paths.
90% of the ENOENT messages are normal and expected. See the output of

Code: Select all

strace -e file -o work.txt drakconf

from a working system attached.

Bah. This is bonkers.

Is a reinstall going to be the only way round this.

[DiBosco]

This solved it. No idea why.

xhost +local:root

[neofutur]

same problem here, no way to access any draktools from a console, same error, no sudo or pkexec or gksudo working , until I did :

xhost +local:root

imo this is a huge bug, possibly due to an old config not migrated when I upgraded my mageia.

[DiBosco]

I don't think it's anything to do with upgrading. I always install from scratch (home directory aside) and it's there for me.

Hello..

I am using mageia 7 Cauldron and this bug is still active.

If I disconnect fron the network MCC opens just fine.. But if I connect again it stops working.

xhost +local:root seems to fix the problem too.

it is weird..

BTW.. I am using networkmanager.

Well, nothing has changed, judging by the bugreport: https://bugs.mageia.org/show_bug.cgi?id=16764

Could be the old problem if your hostname changes, as that way the X authorisation also becomes invalid and applications need to be notified for that.
See e.g. https://bugs.mageia.org/show_bug.cgi?id=3782

[DiBosco]

I'm also seeing this persistent bug on the otherwise superb Mageia 7. FWIW, I never see it on desktops, just laptops.

Edit: Reading those posts Doktor pointed to, the hostname seems to be important here. From what I can grasp, it's dependent on the hostname, which if I understand correctly changes as you change network? I suppose if you're on a desktop and that hostname doesn't change because the network doesn't change, but if you move around with the laptop, the network you're attaching to will obviously change.

So, is it possible to set a permanent hostname? Would that possibly fix it? I can see plenty of articles on line about changing this hostname without rebooting, but I can't see anything about its permanency when you move around.

No, it would only do that if you never put a proper hostname in place and accept to get a hostname via DHCP.

Please read up on hostnamectl and /etc/hosts. This was also mentioned in another previous thread: viewtopic.php?f=8&t=12128
