I noticed Settings has gone missing from my ubuntu 18.04. When I click on the spanner icon under the power icon in the top right nothing appears to happen. Attempting to install it fails with: $ sudo apt install gnome-control-center [sudo] password for lucas: Reading package lists... Done Building dependency tree Reading state information... Done Some packages could not be installed. This may mean that you have requested an impossible situation or if you are using the unstable distribution that some required packages have not yet been created or been moved out of Incoming. The following information may help to resolve the situation: The following packages have unmet dependencies. gnome-control-center : Depends: colord (>= 0.1.30) E: Unable to correct problems, you have held broken packages. This may have come about as a side-effect of trying to install simple- scan. I raised a question about that at https://askubuntu.com/q/1108407/103266 but it never got fixed. I couldn't resolve the error "Unable to correct problems, you have held broken packages". Any suggestions welcome, please.
