SUMMARY *** NOTE: If you are reporting a crash, please try to attach a backtrace with debug symbols. See https://community.kde.org/Guidelines_and_HOWTOs/Debugging/How_to_create_useful_crash_reports *** Adding a PPA/repo using Software Sources does not add the GPG key so apt errors out. This maybe an issue with a Ubuntu package but I'm not sure. STEPS TO REPRODUCE 1. Open Discover then click Settings 2. Click Software Sources then click Other software 3. Use the Add button to add a repo like: https://dl.google.com/linux/chrome/deb/ OBSERVED RESULT When you run updates apt is not happy as it is missing the GPG key to use the repo securely. EXPECTED RESULT When you run updates everything is happy. SOFTWARE/OS VERSIONS Linux: 5.15.0-18-generic (available in About System) KDE Plasma Version: 5.24.0 KDE Frameworks Version: 5.90.0 Qt Version: 5.15.2 ADDITIONAL INFORMATION
Yeah, we don't show a UI for you to accept the key. We probably should.
It was tough to tell if this is a Ubuntu issue or upstream. Having a UI would be good indeed.
