Public bug reported: I am happily running Bionic 18.04 Kubuntu (all previous bugs resolved). I decided to upgrade to Focal 20.04 and got a failure for an unsolvable conflict. I discovered a ppa for xenial was the cause. I removed that and then retried. (All my ppa were now for Bionic so it seemed safe)

If I were to put Focal ppa in my /etc/apt/sources.list there would likely be havoc! pulseaudio currently does not work so I am using alsa. I do not know haw many other Focal elements will emerge even if I can resolve these, Additionally, I do not know how to fix these anyhow. ** Affects: linux (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1917283 Title: "The following packages have been kept back:" bionic requesting focal downloads Status in linux package in Ubuntu: New Bug description: I am happily running Bionic 18.04 Kubuntu (all previous bugs resolved).
