aptitude upgrade vs. apt-get upgrade

[Thomas Hungenberg <th+lists-debian@demonium.de>]

Hi,

since upgrading from lenny to squeeze, I've noticed several times that aptitude
does not install all available security updates whereas apt-get does.

Currently, this looks like:

# aptitude -s upgrade
The following packages will be upgraded:
  bind9-host dnsutils libbind9-60 libdns69 libisc62 libisccc60 libisccfg62 liblwres60
8 packages upgraded, 0 newly installed, 0 to remove and 1 not upgraded.

# apt-get -s upgrade

tex-common
9 upgraded, 0 newly installed, 0 to remove and 0 not upgraded.

What's the reason for this?
