Re: Problem loading Team Fortress 2
Have you tried:
That does not upgrade to a different distribution (unless you changed your sources.list) it is just smarter about resolving changing dependencies for your current Ubuntu version.
sudo apt-get update && sudo apt-get dist-upgrade
Or if you are running 64-bit, maybe you need to install ia32-libs-multiarch. Steam is 32-bit and I already had that installed when installing Steam beta a couple of weeks ago (since updated to release). Also what video card and driver do you have, because they recommend running most recent (experimental) drivers, at least for my nvidia.
I have been running tf2 in 64-bit 12.04 since late January.
