What do the various dpkg flags like 'ii' 'rc' mean?
The first letter displays what is the expected status of the package.
The second letter displays what is the current status of the package.
So for example:
ii means 'It should be installed and it is installed' whereas
rc means 'It's removed/uninstalled but it's configuration files are still there'
