I'm running Steam for Linux (native, not Wine) on Ubuntu 12.10 32 bits. Since the last Steam update, it doesn't work anymore. Instead of starting, it pops a terminal claiming that it needs to install an additional package. Unfortunately, the operation doesn't work. Here's the output:
Steam needs to install these additional packages:
steam-launcher
[sudo] password for tvuillemin:
Reading package lists... Done
Building dependency tree
Reading state information... Done
E: Unable to locate package steam-launcher
Press return to continue:
My OS is up-to-date. I tried to reinstall Steam both from the Ubuntu Software Center and from the Steam website, but I got precisely the same error. I also looked for a repository with this package, but I didn't find anything relevant.
Any clue? Thanks in advance.
