Looks like it might be a good idea to get rid of sessioninstaller, since GNOME Software provides the PackageKit session interface properly already - but since Ubuntu doesn't use the PK backend of GS, I assume that the PK session API will also not work in Ubuntu's version of GNOME Software. Maybe try uninstalling sessioninstaller and see if GNOME Software pops up with the right package or at least an error message.
I guess this problem might only really be fixed by switching GS to use PK or alternatively make the PK session interface work in GS by other means (or, of course, by fixing sessioninstaller, but since that thing is essentially dead I assume that this would not be a viable option). ** Changed in: packagekit (Ubuntu) Status: New => Invalid ** Also affects: sessioninstaller (Ubuntu) Importance: Undecided Status: New ** Also affects: gnome-software (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gnome-software in Ubuntu. https://bugs.launchpad.net/bugs/1661371 Title: [zesty] doesn't offer a window to install missing gstreamer codecs To manage notifications about this bug go to: https://bugs.launchpad.net/packagekit/+bug/1661371/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
