Description Patrick Silva 2020-05-22 17:01:58 UTC
SUMMARY
If there are updates for addons from KDE Store installed on our system,
Discover will not find them until we open their respective "Get new <addon>" windows in system settings.

STEPS TO REPRODUCE
1. install some plasma addon (plasma style or icon theme, for example)
via "Get new <addon>" window in its respective kcm in system settings
2. wait for a update for the just installed addon to be released
3. open Discover and wait it to fetch updates (Discover doesn't find any update for your addon)
4. close Discover
5. open the "Get new <addon>" window used in the step 1 and wait the addons info to be loaded
6. close both "Get new <addon>" window and system settings
7. reopen Discover: now it finds the addon update as expected

EXPECTED RESULT
Discover should always find updates for addons installed from KDE Store.

SOFTWARE/OS VERSIONS
Operating System: Arch Linux 
KDE Plasma Version: 5.18.90

Load the KNewStuff updates information on Discover startup

Without this, Discover only loads the installed items, but does not
also check whether there are updates available. This is cached by
the KNSCore::Engine, so we don't need the throttling in Discover itself,
but also if this is not done during the initialisation step, the updates
information will simply not be available.
