Description yizel7 2021-11-09 20:00:35 UTC 
When using Discover and various updates are found for both flatpak apps and runtimes. If the user click on the "All updates selected" checkbox at the bottom to deselect everything. Followed by selecting various available updates to update, then when the screen refreshes with updates available, the runtime section aka "System Updates" disappears and only the top section for "Application updates" remains.

The user then needs to close Discover and reopen (thereby Discover doing another update check) the rest of the runtimes that were available for updates under "System Updates" will be shown again.

STEPS TO REPRODUCE
1) Wait a couple days for flatpak updates to build up if needed
2) Launch Discover
3) Uncheck the "All updates selected" checkbox at the bottom that is selected by default
4) Select a couple updates to do either in Application Updates or System updates. Just make sure to leave some system updates so we can see the section vanish in the next step
5) Click on the "update Selected" button in the top right
6) Wait a couple seconds or minutes depending on your hardware specs and network speed

OBSERVED RESULT
After doing a partial update (not an Update all) the System Updates section vanishes.

EXPECTED RESULT
When the screen refreshes after a partial update, the user would be able to select both System updates and Application updates.

I cannot reproduce.

Can you confirm you can reproduce this when running "plasma-discover --backends flatpak"? Or does flatpak and packagekit need to be on for the issue to happen?

Should this work on all distros? I ran the command "plasma-discover --backends flatpak" and it did launch Discover however after a couple seconds the loading icon disappears and I get taken to the home of Discover along with this output in Konsole:

plasma-discover --backends flatpak
kf.kirigami: Units.devicePixelRatio is deprecated (since 5.86 ): This returns 1 when using Qt HiDPI scaling.
file:///usr/lib/qt/qml/org/kde/kirigami.2/private/PrivateActionToolButton.qml:74:5: QML Binding: Binding loop detected for property "value"
took really long to fetch FlatpakBackend(0x5654d89ec8d0)

I am not sure how it could have taken "really long" to fetch FlatpakBackend when it only attempted for about 2-3 seconds.

Sorry, that was the wrong command. Try `plasma-discover --backends flatpak-backend`. This should work on all distros with the flatpak backend installed.

How can I confirm I have the flatpak backend installed? I am on an updated Arch Linux.

The same things happened with the above command as opposed to the previous one. Discover stops trying to load after 2-3 seconds and takes me to its home page. The  following is shown in Konsole again:

plasma-discover --backends flatpak-backend

`plasma-discover --listbackends` will tell you what backends you have.

It looks like I have the flatpak-backend, so I am not sure why the command is failing saying it's taking too long when it isn't even really trying. Any ideas?

plasma-discover --listbackends
 * flatpak-backend
 * fwupd-backend
 * kns-backend
 * packagekit-backend
Comment 7 Nate Graham 2021-11-12 17:00:23 UTC 
If `plasma-discover` is already running in the background due to another bug, you'll need to kill it manually with `killall plasma-discover`.
Comment 8 Nate Graham 2025-09-23 18:39:15 UTC 
A lot has changed since it was reported; can I ask you to see if this is still an issue with Plasma 6.4 or later? Thanks a lot.
