What I meant by "[this bug] currently prevents do-release-upgrade to 21.04 from 20.10" is:

If, as I write this, on a (non-Apple) ppc64el platform running 20.10, one attempts to use "do-release-upgrade" to upgrade to 21.04, the upgrade will not proceed, and instead this message will appear:

Does that answer your question?

In case it helps:

1) the "shim" package is _not_ installed on this system (which I guess isn't surprising, given that it doesn't use any of EFI, UEFI, grub etc. to boot...)

2) I believe I have the latest version of ubuntu-release-upgrader, my system reports:

# ubuntu-release-upgrader-core is already the newest version (1:20.10.12)
