[SOLVED] MCC won't open

[z]

This problem started right after I installed a printer. Ever since, I am unable to open MCC. If I click the icon on the desktop, the authentication window opens, I type in the root password, then nothing happens. Systemd logs:

And yet, there's no MCC, just the desktop. I uninstalled the printer and CUPS, since that was the only thing I changed before this problem appeared, and it made no difference. I'm using MATE.

Can you please post the output of

Code: Select all

hostnamectl

This is probably the same issue as in viewtopic.php?f=7&t=13058 - please read the explanation and also the links there.
The fix is to set a proper hostname once, and that's it. If that doesn't help, please provide the output of the commands that I've asked for in the other thread, thanks in advance.

Yep, looks like that was the issue. Thanks!
