  It shouldn't matter which frontend you use.  All the major frontends
check the signature of the Release file when you download package lists
from the archive.  The Release file contains a cryptographic checksum
for the Packages file, which contains checksums for each individual .deb

  dpkg performs no key checking, at least on packages in the Debian
archive.  There was some experimental code to stick embedded signatures
into .deb files, but I don't know what it's status is and packages
containing signatures aren't allowed in the archive last I heard.
