System Settings won't start, Ubuntu 16.04

Title says it all.

I did sudo apt-get upgrade and sudo apt-get autoremove and all that stuff, but System Settings still won't open.

I tried opening it from a Terminal, and it returned Bus error (core dumped)

Any help would be appreciated!

Try this,

sudo apt-get remove unity-control-center
sudo apt autoremove
sudo apt-get install unity-control-center

It worked for me.

And if you are trying to do this with Ubuntu 18.04, try this:

sudo apt-get remove gnome-control-center
sudo apt autoremove
sudo apt-get install gnome-control-center

This is because Ubuntu decided to switch their user interface from Unity to Gnome.

I had a similar issue in Ubuntu 20.04 and I run the following command,

dconf reset -f /org/gnome/control-center/

Note: If this works for you, that's great!!! Honestly, I don't know what does it do in behind the scenes.

With NVIDIA graphics I had to install proprietary nvidia-driver-430.40

I added repositories:

sudo add-apt-repository ppa:graphics-drivers/ppa
sudo add-apt-repository ppa:oibaf/graphics-drivers

and ran

sudo ubuntu-drivers autoinstall

and reboot

The problem was solved.

If does not work for you. To remove the PPAs run:

sudo ppa-purge ppa:graphics-drivers/ppa
sudo ppa-purge ppa:oibaf/graphics-drivers
