Cannot install steam due to missing i386 packages

[maeries]

Hi,

I've reinstalled Ubuntu 64bit a few days ago and since then I cannot install steam

:~$ sudo apt-get install steam

And apt-get -f install doesn't do anything

:~$ sudo apt-get -f install

Do you have any idea how to solve this?

Have you updated your sources since reinstalling?

sudo apt-get update && sudo apt-get dist-upgrade

Also I think it's best to get the latest steam*deb from Steam's site, http://store.steampowered.com/about/ click 'Install Steam Now'. Let us know if it works or not.

Yes, i ran apt-get update, apt-get (dist-)upgrade, apt-get autoremove and apt-get -f install nearly 100 times.

So, I downloaded steam from steampowered.com and it kinda works. I can start it, but at every start I get this

Steam needs to install these additional packages: 
    libgl1-mesa-dri:i386, libgl1-mesa-glx:i386

Notice that it says here "held broken packages" while steam says only "held packages"

I found something I don't understand. I have to install libdrm2:i386 to get steam working

:~$ sudo apt-get install libdrm2:i386

But why does thin not work? I have kmod, upstart, libqt5feedback5 and libqt5multimedia5 installed.

Anyone any idea?
