Ubuntu – I cannot open system settings in ubuntu 17.10

system-settings

When I chose settings from taskbar menu nothings happened. I have been working a while ago, last think that I did was removing ~/.pulse directory and run pulseaudio -k and pulseaudio --start (from this thred – No sound after update to ubuntu 17.10).

I can see error in logs when I click setting button (journalctl /usr/bin/gnome-shell -f -o cat):

JS ERROR: TypeError: app is null

Reinstall the Gnome Control Center using :

sudo apt install --reinstall gnome-control-center

I noticed in the comments TuKsn mentioned to use

gksu unity-control-center

You said this came up with an error. Instead, try the following:

sudo apt-get install unity-control-center

If you do not yet have it installed, it will ask if you wish to install it (y/n). If you do have it installed, which is likely, it will make sure you have the newest version. Some of the solutions found at Missing System Settings after removing some packages may also help.

Ubuntu – Ubuntu 14.04 + Gnome 3.10 = cannot open settings

Firstly, I ran:

sudo dpkg-reconfigure gnome-control-center

It didn't help so i ran this one and it solved my problem:

sudo apt-get -f install --reinstall gnome-control-center

I hope it will help someone in the future.
