error 1.0.0 -> 1.0.3

[Zeitkind]

If you're (like me..) still running Etch for some reasons, it's a good idea to add some repositories:

#volatile
deb http://volatile.debian.org/debian-volatile etch/volatile main contrib non-free
deb http://volatile.debian.org/debian-volatile etch/volatile-sloppy main contrib non-free

#Backports
deb http://www.backports.org/debian etch-backports main contrib non-free

Volatile is for newer versions of eg. clamav and backports adds some newer stuff - like the one missing for the 1.0.3.1 update.
Backports are not installed automatically, you have to force install by giving the source:

apt-get -t etch-backports install libapache2-mod-fcgid

And before, you should also install the keyring:

apt-get install debian-backports-keyring

I had some other minor issues (like a double entry in named.conf), but that might be because of the failed updates. Another thing that was not so good: the update overwrote my main.cf from postfix without making a backup before (but I did...). I had enabled TLS and had added a bunch strict rules (like smtpd_junk_command_limit = 10) and some whitelist stuff (like check_client_access cidr:/etc/postfix/postfix-dnswl-permit) and enabled amavis. So check your postfix after the update (postconf -n).
