I'm on a new install of Lubuntu 12.04 on an Acer Aspire 5534 (specifications here, tl;dr: AMD dual-core 64bit) trying to install steam_latest.deb from the Steam website. When I open gdebi to install, it tells me that it's uninstallable because it's for a i386 architecture. I've tried installing ia32-libs (installed, no success), gdebi --add-architecture i386 (with and without --force, command unknown). This is all I've found to fix the problem, but none of it has worked for me. Any suggestions are welcome, thanks for your time.

Does this answer work for you? – Glutanimate Dec 30 '12 at 21:35
Package libjpeg-turbo8:i386 is not available, but is referred to by another package. This may mean that the package is missing, has been obsoleted, or is only available from another source E: Package 'libjpeg-turbo8:i386' has no installation candidate – Ian Dec 30 '12 at 21:56
do sudo apt-get install steam:i386 – dat tutbrus Jan 23 at 7:14

Some similar questions have already been asked here.

The problem, in short, is trying to force the installation of a 32 bit package on a 64 bit machine.

I would suggest you to have a look at these questions:

The only thing that began to work was However, there was a failure on step 1 part 4. Not sure where to go from here. – Ian Dec 30 '12 at 21:54
Read the terminal output, sometimes it's a recursive dependency of a dependency if you catch my drift. Install the missing package & voila! – fleamour Apr 30 '14 at 12:11

You could do this:

Dowland the package from

and then appgrid

sudo apt-get install appgrid


sudo dkms-reconfigure steam
sudo apt-get install --reinstall steam
sudo apt-get update 
sudo apt-get upgrade 
sudo apt-get dist-upgrade 

and it might work fine this way.
