Alright so my computer is 64-bit and I only want to use Linux to install Steam, play Team Fortress 2 and get that penguin item but It's not working out for me. The version of Ubuntu I installed was the "Wubi.exe" which let's me use it along with Windows. But when I get it up and download the Steam .deb file, it tells me "Wrong Architecture 'i386'". What do I have to do to run Ubuntu alongside windows without using a CD/USB stick?

Open the terminal and type:

sudo dpkg --add-architecture i386
sudo apt-get update

Try installing it after doing that.

For future reference look: https://wiki.ubuntu.com/MultiarchSpec & https://help.ubuntu.com/community/MultiArch

    It worked fine here when I've ran into the problem. (And It's the way many people fixed it) – Blastcore Feb 16 '13 at 23:18
  • @user132730 after doing that run sudo apt-get install ia32-libs as has been suggested by lordqwerty. – w4etwetewtwet Apr 7 '13 at 14:41
  • recent versions of Ubuntu supports multiarch natively (both precise and trusty), you just need to apt-get install steam. – Giovanni Toraldo Jun 7 '14 at 10:39

EDIT [Preferred Method on new Ubuntu]

As of Ubuntu 16.04 you can now do the following:

$ sudo add-apt-repository multiverse
$ sudo apt-get install steam

OLD ANSWER:

Try installing the ia32 libs by opening up a terminal and entering the following:

$ sudo dpkg --add-architecture i386
$ sudo apt-get update
$ sudo apt-get install ia32-libs

Once that has run and installed, then use terminal to install Steam for you. Run the following in terminal:

$ sudo apt-get install steam

Now you will have Steam installed and you should be able to launch it as expected.

sudo dpkg --add-architecture i386
sudo apt-get update
sudo apt-get install lib32z1 lib32ncurses5 lib32bz2-1.0
sudo apt-get install steam

it's working with Ubuntu 14.04 LTS on iMac 2008 via Dual-boot with rEFInd.

  • Thank you i was looking for the solution for 14.04 64bit everywhere. Yours worked. – samy Feb 4 '16 at 23:04

Not sure about in 14.04, but at least in 15.04 steam is in the multiverse repository. that means that you can simply sudo apt-get install steam and it will install the required dependencies. No need to download a .deb file.

Just adding this for future use.

sudo dpkg --add-architecture i386
sudo apt-get update
sudo apt-get install lib32z1 lib32ncurses5 lib32bz2-1.0
sudo apt-get -f install steam

This worked for me, finally after searching around for a few hours. Thank you guys!

Talk of i386 or ia32-libs doesn't work for 14.04. When I try the later, I receive the following output: However the following packages replace it: lib32z1 lib32ncurses5 lib32bz2-1.0

As such, this solution works for me. Alt+Ctrl+T to open the terminal and run following commands:

sudo apt-get install lib32z1 lib32ncurses5 lib32bz2-1.0
sudo apt-get install steam

Steam works as expected from here.
