I upgraded from Ubuntu 16.04 to 17.10, via 17.04. After the upgrade, I cannot access the system settings window. When I try to open it through the terminal, this is the error produced.

anomitra@C3PO:/usr/lib/x86_64-linux-gnu$ [INFO 14:56:15.591156] Application.vala:153: System Settings version: 2.0 [INFO 14:56:15.591186] Application.vala:155: Kernel version: 4.13.0- 16-generic [WARNING 14:56:15.635521] PluginManager.vala:115: Unable to scan plugins folder: Error opening directory '/usr/lib/x86_64-linux- gnu/pantheon-online-accounts': No such file or directory [FATAL 14:56:15.711890] PlugsManager.vala:58: get_plug () not found in /usr/lib/x86_64-linux-gnu/switchboard/system/pantheon- useraccounts/guest-session-toggle [ERROR 14:56:15.717373] [GLib-GIO] Settings schema 'org.pantheon.dpms' is not installed

Any help would be appreciated. Thanks!

You can try to reinstall gnome-control-center from terminal:

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