Bug#65438: apt: "should I get this package" algorithm is wrong

[dwitch <ydirson@altern.org>]

Package: apt
Version: 0.3.19

There is currently an inconstency between potato and woody: 

lftp ftp.debian.org:/pub/debian> dir dists/woody/main/binary-i386/admin/ana*
-rw-rw-r--   1 ftp      ftp         21770 May 25 18:52 dists/woody/main/binary-i386/admin/anacron_2.1-5.1.deb
lftp ftp.debian.org:/pub/debian> dir dists/potato/main/binary-i386/admin/ana*
-rw-rw-r--   1 ftp      ftp         21792 May 29 16:46 dists/potato/main/binary-i386/admin/anacron_2.1-5.1.deb


That is 1 only version number for 2 different contents (just reported
against ftp.d.o and anacron).

What apt does, when one of the dists is active in apt.conf, and
anacron is in sync with this dist, and I switch to the other dist, is
"upgrading" to the one in the other dist.  It works both ways, so I
suppose the only check for an upgrade is "proposed package is
different" (based on what ?), and test on version is ">=" where it
should be ">>".

to finding flaws"  :)
