> @Alessandro, it seems the new fix isn't in questing/resolute yet?
Right, sorry.
Opened a new merge proposal for questing too. For resolute, packagekit should
be synced from debian instead (thus "Fix Committed").
** Changed in: packagekit (Ubuntu)
Status: Fix Released => Fix Committed
** Changed in: packagekit (Ubuntu)
Milestone: ubuntu-25.10 => ubuntu-26.04
** Description changed:
[ Impact ]
While attempting to play a video on Ubuntu noble desktop for raspberry
pi, totem attempts to locate a package for the H.264 codec but cannot
find a service providing org.freedesktop.PackageKit.
The main source of the bug is that App Center does not implement
org.freedesktop.PackageKit.Modify2 on the session bus, which would
prompt the user to install the missing codecs. This is being worked on
and will be delivered as a snap update.
But a fix to PackageKit itself is also necessary in order to correctly
resolve the codec providers.
[ Test Plan ]
For the purpose of the SRU, we're only going to verify the PackageKit fix.
- Verify the output of the following commands:
+ On both AMD64 and ARM64, verify the output of the following commands:
1. $ pkcon what-provides
"gstreamer1(decoder-audio/mpeg)(mpegversion=4)()(64bit)"
-> gstreamer1.0-fdkaac-*.amd64
-> gstreamer1.0-libav-*.amd64
-> gstreamer1.0-plugins-bad-*.amd64
-> gstreamer1.0-plugins-good-*.amd64
2. $ pkcon what-provides "gstreamer1(decoder-audio/mpeg)(mpegversion=4)"
-> gstreamer1.0-fdkaac-*.amd64
-> gstreamer1.0-libav-*.amd64
-> gstreamer1.0-plugins-bad-*.amd64
-> gstreamer1.0-plugins-good-*.amd64
Additionally, if you have enabled the i386 dpkg architecture on amd64:
-> gstreamer1.0-libav-*.i386
-> gstreamer1.0-plugins-bad-*.i386
-> gstreamer1.0-plugins-good-*.i386
3. $ pkcon what-provides "gstreamer1(decoder-video/x-h265)()(64bit)"
-> gstreamer1.0-libav-*.amd64
-> gstreamer1.0-plugins-bad-*.amd64
4. $ pkcon what-provides "gstreamer1(decoder-video/x-h265)"
-> gstreamer1.0-libav-*.amd64
-> gstreamer1.0-plugins-bad-*.amd64
Additionally, if you have enabled the i386 dpkg architecture on amd64:
-> gstreamer1.0-libav-*.i386
-> gstreamer1.0-plugins-bad-*.i386
[ Where problems could occur ]
The patch can only affect the behaviour of matching GStreamer capabilities.
No other packagekit features are affected.
Problems could manifest with `pkcon what-provides gstreamer1(...)` queries
returning the wrong package names. This is verified in the test plan.
