Ubuntu – Missing System Settings after removing some packages


I installed or uninstalled some packages. I do not even remember what I was doing. As a result, now I can't see most of the system settings in settings window.
Any idea how to solve this problem.

When I hover mouse over the window title, it shows 'Unknown Application name'
I must have removed something, not sure what 🙂

You may have accidentally removed some packages (or some dependencies which caused the package to uninstall). In any case, you may try installing (or re installing) the package ubuntu-desktop. Correct any accidental package uninstallation by:

sudo apt-get install ubuntu-desktop
