"What am I doing wrong?"
Well, it looks like you have mixed up a Ubuntu installation with lots of third party (Dotdeb / debian) packages and ended up in DEB-hell.
Sidenote: The packages from Dotdeb should work on Ubuntu, but no additional support will be provided.
Anyway, installation of
ia32-libs on Ubuntu should look somewhat like this, when used with the
no-install-recommends switch enabled:
# apt-get install --no-install-recommends ia32-libs
Reading package lists... Done

The following NEW packages will be installed:

Do you want to continue [Y/n]?
Only 10 new packages needed on my Ubuntu 10.04.4 amd64 here.
From my point of view a clean installation of your "Enemy Territory" Ubuntu-server is the safest way to go. De-installing the dotdeb packages (PHP and MySQL-packages) and start from scratch with different, official repositories is another way.
Or install Debian on the VPS and use the Dotdeb-repository.
