unrar-2.80 packaging

Hi there,

For the last while dselect (yes I am old fashioned) has been throwing out
warnings about unrar-2.80 every time I run it. It's nothing serious, just a
little bit annoying.

Looks like this:

warning, in file '/var/cache/apt/available' near line 745160 package
'rar-2.80': missing architecture

Is there any easy fix?

Mark
