I am not sure, but it may be related to this issue: https://pagure.io/fedora-kde/SIG/issue/134

Could someone please confirm that they were able to update a clean Fedora 35 Kinoite installation using GUI?

I have updated the system to a latest one two days ago. Today, I have checked for new updates and Discover again found no new updates. Running "rpm-ostree upgrade" returned a couple of updated packages.

It looks like that system updates on Kinoite do not work at all when using GUI and have to be always done in terminal.

Support in Discover is still WIP. See https://pagure.io/fedora-kde/SIG/issue/112.

Regarding the rpm-ostree support in Discover, please see my comment here:

Thanks!

https://invent.kde.org/plasma/discover/-/merge_requests/166 has been merged!
We're getting closer to proper support. I have a couple of things left to fix but hopping to get everything done for 5.27.

Next step in https://invent.kde.org/plasma/discover/-/merge_requests/403

PR above has been merged and I can now update and rebase to newer versions with Discover. Next steps are fixing the notifier and adding support for settings. Targeting this for 5.27 and will be made available everywhere we make 5.27 available.

Next steps in:
- https://invent.kde.org/plasma/discover/-/merge_requests/407
- https://invent.kde.org/plasma/discover/-/merge_requests/408
- https://invent.kde.org/plasma/discover/-/merge_requests/409

Last missing piece is a setting for auto updates or auto download of updates.

Code is almost fully merged. On to the next steps:

• Re-enabling the backend in Rawhide on Kinoite: https://pagure.io/workstation-ostree-config/pull-request/315
• Backports for Discover 5.26 in Rawhide only coming right after

OK, it's a little bit harder as expected to backport so I'll make a scratch build to overlay instead.

I wrote a blog post about this work: https://tim.siosm.fr/blog/2022/11/22/rpm-ostree-support-in-discover/

This is amazing work @siosm thanks so much for making this a reality whenever Kinoite updates to 5.27!

If Discover detects a new rpm-ostree commit available, does it trigger the toaster notification that updates are available since it has an 'Operating System' category much like Discover currently does when Flatpak updates are available?

Yes, it will trigger the same notifications.

I'm now working on background / silent / auto-updates support.

Closing as this is going to be fixed when we update to 5.27 and I likely won't be able to backport support before it happens.
