Re: dftp problem...D
I really haven't used dftp for a while myself, but according to the man
page, the clear option doesn't clear uninstalled packages from the
dftp uses it's own /root/packages/.installed file to know what packages
are installed. It may have been that your dftp /root/packages/.installed
file was out of sync with the dpkg data base. The dftp scaninst command
should be run as the first step in a dftp session. That uses information
from dpkg to create the .installed file.
There is also a dftp verify command that should be run after downloading
but before unpacking. The dftp man page explains it all pretty well.
