Well, actually this is probably incorrect. It could also be on hold.
And I'm not sure what "Desired action" means exactly. If locales-all
is marked for installation in dselect, will this be "i"? In such a
case, using "Desired action" is not possible; see:

  https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=840901

Perhaps a combination of flags of "Package status"...
'^.[UFWti]'?
