Unable to install language packs

I have found that on my Ubuntu GNOME 17.04 installation with GNOME 3.24.1 that if I open the "Region & Language" section of the gnome-control-center that even though in Terminal it is indicated that there are Enlish (UK) packages to install, it doesn't do anything in the GUI. And if I attempt to install a new language the whole window just really quickly flashes once but nothing else happens. Here is the output from Terminal:

    ** (gnome-control-center:9685): WARNING **: Ignoring launcher gufw (missing desktop file)

    ** (gnome-control-center:9685): WARNING **: Ignoring launcher landscape-client-settings (missing desktop file)

    ** (gnome-control-center:9685): WARNING **: Ignoring launcher language-selector (missing desktop file)

    (gnome-control-center:9685): common-cc-panel-WARNING **: Language ja_JP not installed, trying to install it

I know other people who are experiencing this issue and the only way for them to install new languages is to install the gnome-language-selector from Unity.
