SUMMARY

For the past few weeks, there have been updates to several Plasmoids (Air Quality Widget, Media Controller Compact, Window Buttons Applet, Window Title Applet) that I downloaded from store.kde.org sitting in the update queue. Every time I attempt to update all, it hangs with 0% in the task bar and refuses to allow me to cancel any task. When I attempt to remove the Plasmoids through Discover it hangs at 0% and does not allow me to cancel the task. If I unclick the Plasmoids (it appears to be all of them) in order to update other packages as soon as I click "update all" they are re-enabled against my wishes and the process hangs at 0%. I've been just updating my system using apt in the meantime.


STEPS TO REPRODUCE
1. Selectively attempt to update each of the 4 Plasmoids individually, as a whole, and attempts to uninstall
2. Observe task stuck at 0%


OBSERVED RESULT

System refuses to close or progress. "Logout cancelled by usr/bin/plasma-discover"

EXPECTED RESULT

Plasmoids should be able to be either updated, uninstalled, or at the very least ignored through Discover
