404 on the download link.

The forum is bad about punctuation:
http://media.steampowered.com/client/installer/steam.deb

It says that I cannot install "libgl1-mesa-dri:i386".

I tried it but I got this error

(Reading database ... 173326 files and directories currently installed.)

Edit:
Also, after trying to run whatever it managed to install, it came up with a bunch of errors when trying to get libraries, I would post it, but its too long. Also after I exit out of it, it says "You are missing the following 32-bit libraries, and Steam may not run:
libGL.so.1" but after trying to install it, I can't because of dependency problems.

Are you using the proprietary drivers from nvidia?

First of all, I am using AMD and second, after reinstalling ubuntu I was able to successfuly install steam

I use proprietary and had this problem. What I did was delete the libgl1-mesa:i386 dependencies. That included the ia32-libs. Next, I reinstalled the nvidia driver. Then I reinstalled the mesa back. It worked. This is just you know. I'm glad you found a solution.

I figured one thing out from this, don't delete any packages that you don't know what they are, like one that is, name I think it was something like, libxdamage. Sounds like a virus, but is an essential part to your os apearently...

LOL. Viruses are virtually non-existent for Linux, so don't worry about that. But absolutely never delete anything in Linux if you don't know what it is.

It "works" if I use the steam.deb, but it still downgrades a bunch of xorg packages! Valve, please update steam to be compatible with 12.04.2, as it is steam installer seems hardcoded to detect certain package names, so when it sees 12.04.2's newer xorg packages that have "-lts-quantal" at the end, it downgrades them to the old 12.04.1 versions, and this is totally counter productive because the newer 12.04.2 packages are better for games!

The same issue is happening to me. I had to install the newest version of Ubuntu anyway... and I'm running it alongside Windows 8. Both are 64-bit architecture. If I try to download the 32 bit version (EDIT: of Steam), It says that I have the wrong architecture.

Try this

sudo apt-get install -f
sudo dpkg --configure -a

it solved my problems :)

A lot of problems could be solved immediately, if the Steam guys would just compile steam for amd64. Can't really be that hard. If you give me the source code, I'll do it. ;-)

@Valve: If you simply update Ubuntu 12.04/12.04.1, there are no chances and Steam will work fine. The new Ubuntu 12.04.2 includes a backported graphics/kernel stack from Ubuntu 12.10 so it works on newer hardware. It uses packages that end with -lts-quantal (e.g. xserver-xorg-core-lts-quantal). You need to adapt the dependencies of the Steam .deb to reflect those changes and push the new version on the website *and* the Ubuntu Software Center.

Linky-link worked.
