Flatpak update not displayed in GNOME Software
Description of problem:
It seems that Flatpak updates are not showing in GNOME Software on Fedora Rawhide Silverblue. See the attached screenshot. I have tried restarting the gnome-software process and the whole computer as well, but GS still didn't show the org.kde.Platform update. I currently don't have any app that actually uses the KDE Platform runtime installed, so I am not sure if GS actually updates runtimes that are unused.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Use latest Fedora (Silverblue) Rawhide with Flathub repo added and some Flatpak apps/runtimes installed.
2. Wait for some Flatpak app/runtime update (periodically run "flatpak update" from terminal).
3. Run GNOME Software, switch to the "Updates" tab and see if there is any update available.
Some updates are not displayed in the "Updates" tab.
All updates are displayed in the "Updates" tab and available for installation.
I just got the same issue with org.kde.Platform update not showing in GNOME Software on Fedora Silverblue 29 with gnome-software-3.30.6-1.fc29.x86_64. This time it was on a machine that had actual applications (org.telegram.desktop) using the runtime installed. Weird thing is that on another machine with standard Fedora 29, the org.kde.Platform update was displayed without any issue in GS.
Could it be user vs system installation that breaks it?
Hmm, I am not sure. The only difference between the Silverblue machine and the regular Fedora one is that the Silverblue machine has Flathub repo added as a system repo (and no user repos) while the regular Fedora machine has Flathub repo added as user repo (and no system repos). :)
Hmm, I just got some Flatpak runtime updates and they all were displayed in (and updated with) GS without any issues. So the only problem seems to be with the org.kde.Platform* ones.
Hmm, and now I got no updates in GS (on the Silverblue Rawhide machine) although there was 7 Flatpak updates available (including apps such as GNOME Chess). Restarting GS process didn't help and there was nothing in the GS log. Weird.
Ignore my previous comment, it is a different issue (probably caused by a broken Rawhide), not related to the org.kde.Platform* one.
