SUMMARY In 40% of all tries the update fails: no password dialog is presented to the user. STEPS TO REPRODUCE 1. I start discover with the icon next to the clock 2. Dialog says: "Aktualisierungen werden gesucht" (updates are searched) 2. When it is finished, I press on "Alles aktualisieren" (update everything) OBSERVED RESULT - nothing happens - When I click on "Aufgaben" (Tasks) I get the info: "Aktualisieren: wird installiert" (Installation in progress) - the only way to close Discover is with the task manager (CTRL+ESC) EXPECTED RESULT The password entry dialog should be presented, so I can enter the sudo-password! SYSTEM INFORMATION I run Kubuntu 18.04 uname -a gives me: 4.15.0-42-generic #45-Ubuntu SMP Thu Nov 15 19:32:57 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux
I have seen this happen in 5.14.4 too from time to time. Like Leon says, it's not consistent. 40% reproducibility feels about right though.
What's happening here is that the update state is dirty, so Discover checks for updates again to get a clean state. Only *then* will it allow you to actually use the button to do what it says it will do. Needless to say, this is not ideal and will be fixed.
This is no longer an issue now that we gate the update page on having all updates already collected.
