Suppose I accidentally delete a file, and I wish to reinstall that file
from the current rpm that provided the file.

Is there a way to use rug to either replace the file, or to download the
rpm? If I try to reinstall with rug, I'm told, for example:

ERROR: There is no newer version of 'nici' in any subscribed channel

Can I do a forced reinstall without first uninstalling the package (and
any dependent packages) ?
