This is probably for the fix of #819636, maybe the check is too
expensive and not worth it after all.

(In my not-bleeding-edge system takes 1s or a fraction, not several

As a work-around, disabling "Install recommends automatically" should
help with the speed, but I'm not sure if you'll want to do this (use at
