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: > An upgrade is not possible at this time > > Due to a bug in shim, LP: #1928434, upgrades are not currently safe > for your hardware. > > Once that bug has been resolved you will be able to upgrade to the > next release of Ubuntu. > > > Restoring original system state > > Aborting 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) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1928434 Title: shim-signed does not boot on EFI 2.40 by Apple To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/shim/+bug/1928434/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
