Ok, I have a partial solution for this in zesty-proposed. (It's in -proposed because it needs an Archive Admin to let the arch:all package depend on an arch:i386 similar to how pixfrogger was handled LP: #1585058)
The problem is the installation fails because of a debconf prompt. I get the popup message displayed below. To duplicate, be sure to first run sudo apt purge steam And to fix apt afterwards, run sudo apt install -f Sorry, this did not work ------------------------ Detailed errors from the package manager follow: Error while installing package: subprocess new pre-installation script returned error exit status 1 -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to appstream in Ubuntu. https://bugs.launchpad.net/bugs/1564570 Title: Gnome Software catalog entry missing for Steam except on i386 To manage notifications about this bug go to: https://bugs.launchpad.net/hundredpapercuts/+bug/1564570/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
