I am trying to restore the unity control center but there are always missing items even after I run:
sudo apt install unity-control-center
and
sudo apt install ubuntu-desktop
And this is what I get:
You can see some items are missing, like Language support, Security & privacy, Additional drivers, Printing, Backups, Software updates
activity-log-managerpackage is installed. If it's not then install it & the Security & Privacy panel should return. If that's the case then the rest of the missing can be returned by finding the missing packages. – doug May 14 '16 at 16:37
