I had the same problem and I decided to replace my version of Kubuntu 19.10 with the latest download of 20.04. So on my Laptop I have two similar versions of Kubuntu 20.04 in separate partitions.
I found it interesting that this new installation did not result in the above reported error, even after installing the majority of packages
.
I had an alternative reason for wanting to have another copy of 20.04 in a separate partition. I was wanting to try the Linux Kernel 5.6 and didn't want to damage my "standard" version of 20.04.
The approach that I have had success at installing Linux Kernel 5.6 can be found at http://ubuntuhandbook.org/index.php/...tu-linux-mint/.

All is working well and I will certainly let you know if I have any problems as Kernel 5.6 has had a good report from phoronix at: https://www.phoronix.com/scan.php?pa...features&num=1
