That bug seems old & ignored. What works here is to install gstreamer1.0-packagekit, then -

Updating plugin registry ... In this case picking the libav plugin allows subsequent playback of that file. When gnome software opens there is a warning - "Sorry, something went wrong You need app-install-data package to be able to look for applications that can handle this kind of file" That seem irrelevant.. Is there some script in this gst package that is missing from gnome- software install? ** Summary changed: - Installation of missing plugins/codecs fails or Why isn't gstreamer1.0-packagekit on default image? + Installation of missing plugins/codecs fails or is gstreamer1.0-packagekit what's needed? -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gnome-software in Ubuntu. https://bugs.launchpad.net/bugs/1712979 Title: Installation of missing plugins/codecs fails or is gstreamer1.0-packagekit what's needed?
