See http://appstream.ubuntu.com/xenial/universe/issues/pcsx2.html on why it doesn't show up.
AppStream on Debian/Ubuntu unfortunately isn't multiarch-aware yet, I am working on that upstream. Won't make it for Xenial though, I think, since it will require several invasive changes. In any case, even with that support PCSX2 wouldn't show up because of the issues linked above. ** Changed in: gnome-software (Ubuntu) Status: New => Invalid -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1575367 Title: Gnome Software catalog entry missing for PCSX2 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-software/+bug/1575367/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
