Public bug reported: I run KDE neon User Edition 5.19 18.04 and have a few PPA's active (OBS, Chrome, VirtualBox, etc...).
When I try to upgrade to KDE neon 20.04 I am met by the error "Could not calculate the upgrade" ant the text "An unresolvable problem occurred while calculating the upgrade. This was likely caused by: * Unofficial software packages not provided by Ubuntu Please use the tool 'ppa-purge' from the ppa-purge package to remove software from a Launchpad PPA and try the upgrade again. If none of this applies, then please report this bug ..." As far as I know I do not have any Launchpad PPA's, but I might be unaware. And ppa-purge did not tell me anything about what package might be the problem. Neither did the logs in /var/log/dist-upgrade. I am by far no power user, and this is as long as I can go on my own. I will probably just reinstall from scratch, but since the error message asked me to report it, I did. Hope it might help in any way.
