EXPECTED RESULT System should be untouched when cancelling out of the upgrade if the upgrade did not proceed. Flatpak and System Information should still work. SOFTWARE/OS VERSIONS Linux/KDE Plasma: 5.19.3 or 5.19.4. Not sure because System Information shortcut is missing. KDE Plasma Version: KDE Frameworks Version: Qt Version: ~$ uname -a Linux <computername> 4.15.0-112-generic #113-Ubuntu SMP Thu Jul 9 23:41:39 UTC 2020 x86_64 x86_64 x86_64 GNU/Linux ADDITIONAL INFORMATION
After rebooting, the system almost unusable. The login screen will show a new interface but I cannot log in because the Enter key does not let me submit the password. Also it defaults to the on screen keyboard. Even when I use the onscreen keyboard, clicking the Enter button does not work. I can still press CTRL+ALT+F2 to get to a console screen and log in.
In the console I did do-release-upgrade and completed the upgrade; however, the login screen still would not let me log in. I deleted ~\.Xauthority but i still couldn't log in Then I did: sudo apt-get update sudo apt-get upgrade sudo apt autoremove sudo apt-get clean reboot Then I didn't get login screen any more. I guess deleting .Xauthority was bad. I'm just going to try to do a clean install of KDE Neon 20.04.
A clean install of KDE Neon 20.04 (2020-08-15) to replace the partition results in a "GNU GRUB version 2.04" screen where I am to enter commands into grub.
A clean install of Kubuntu 20.04.1 including deleting partition and formatting also results in a "GNU GRUB version 2.04" screen where I am to enter commands into grub.
I was able to enter in grub commands by following instructions on https://linuxhint.com/grub_rescue_ubuntu_1804/ I had to change the boot partition to "nvme0n1p6" to match the correct partition instead of "sda1". A problem still exists where the computer does not show a grub boot menu and still goes to the grub command line. In Kubuntu, I also tried to update grub using: sudo update-grub2 but it still requires me to enter commands into grub. I also tried grub-install but it fails: $ sudo grub-install /dev/nvme0n1 Installing for i386-pc platform. grub-install: warning: this GPT partition label contains no BIOS Boot Partition; embedding won't be possible. grub-install: warning: Embedding is not possible. GRUB can only be installed in this setup by using blocklists.

I'm using UEFI and dual boot with Windows 10.
In Kubuntu, I also tried using the EFI boot partition but it still requires me to enter commands into grub when I restart the computer. ~$ sudo update-grub2 [sudo] password for user: Sourcing file `/etc/default/grub' Sourcing file `/etc/default/grub.d/init-select.cfg' Generating grub configuration file ...
