This seems to be due to the fact that Ubuntu ships it's own package manager ( snap-store / Ubuntu software ), and not gnome-software. Installing gnome-software fixes the above dbus error, but the ID3 muxer is still not found.

@seb128: Thoughts ?

Sébastien Bacher:

Thanks for pinging, it does sound a bug on the Ubuntu side instead, we will investigate.

Did you have snap store active when you tried?

Either ways there was no difference.

Trying the following command should invoke gnome-software, but it fails with d-bus error.

# /usr/libexec/pk-gstreamer-install "gstreamer|1.0|rhythmbox|ID3 tag muxer|encoder-application/x-id3"

[crvi (crvi)]

Since, org.freedesktop.PackageKit.service dbus service is provided by gnome-software, it succeeds after installing gnome-software package.

$ apt-file search org.freedesktop.PackageKit | grep /org.freedesktop.PackageKit.service

gnome-software: /usr/share/dbus-1/services/org.freedesktop.PackageKit.service
packagekit: /usr/share/dbus-1/system-services/org.freedesktop.PackageKit.service

testing on hirsute, calling pk-gstreamer-install as described in #3 errors out if snap-store isn't started but doesn't if it is (it still doesn't seem to work correctly but triggers a notifications with actions)

Right. That was weird.

I'm not seeing any notifications here.

Status changed to 'Confirmed' because the bug affects multiple users.
