That's because _test_and_fail_on_apple in DistUpgradeQuirks.py (see line
377) in the upgrader itself, is set to fail if vendor.startswith('Apple
Inc.') OR if vendor is unknown i.e. /sys/class/dmi/id/sys_vendor is null
(for example as it will be in WSL or just about any other system where
DMI isn't implemented). Put a return after that and you should be able
to force it (on your own risk).-- 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
