Created attachment 158009 [details] Update UEFI dbx doesn't work No matter how many times I click "Update All", the "UEFI dbx" item remains in the list as seen in the screenshot. SOFTWARE/OS VERSIONS Fedora 37 KDE spin KDE Plasma Version: 5.27.4
Apparently this was fixed in plasma-discover-5.27.4-2.fc37, which has just been pushed to Stable. I cannot test myself as I do not use plasma-discover.
Can reproduce without that Discover update; unfortunately I broke down and updated with the command line (which required user interactivity, and that's perhaps why it didn't work in Discover) so I can't test it myself. Can you test with the updated version of Discover, Dan?
This is fixed as of 39ac7a6b82b3dc20f3c44ef11246d72545897f2d. It will be part of 5.27.5.
