SUMMARY I wanted to get a newer version of KDE on Kubuntu 20.10, so I was looking for backports or a fresh beta repo. I fiddled with entries on the list, and as with keyboards, cats, and trackpads, some unintentional changes occurred to the settings. They were applied STEPS TO REPRODUCE 1. give password to sudo to look at software sources 2. look away for a split second 3. close the settings 4 see no confirmation 5. wrecked system. This is serious 3. OBSERVED RESULT no error message (I think I changed one thing intentionally but I didn't know if other things had been changed or not) EXPECTED RESULT Do you want to save the changes dialog? or an OK / Apply / Cancel button stack at the bottom. SOFTWARE/OS VERSIONS Windows: macOS: Linux/KDE Plasma: (available in About System) KDE Plasma Version: KDE Frameworks Version: Qt Version: ADDITIONAL INFORMATION
