I ran into this same problem when doing a release upgrade on an AWS EC2 instance. I have not been able to fix a broken upgrade, but here is how to do a successful upgrade.

An "ls" on a brand new EC2 instance running 20.04.1 shows this:

$ ls -lat /var/lib/dpkg

Trying to run a "do-release-upgrade" will not work if any 20.04.01 packages need to be upgraded. If "sudo apt upgrade" is run, "ls" now shows this:

$ ls -lat /var/lib/dpkg
total 1752

Proceeding with "do-release-upgrade" at this point breaks. But if I "sudo unlink /var/lib/dpkg/dpkg" before doing the "do-release-upgrade", the upgrade to 22.04 is successful.
