@xypron, I must admit this low-level firmware stuff is definitely outside of my comfort zone. That said, I'm fairly certain about the cause and likely fix as it was confirmed empirically.
So I've only tested with the LXD snap. Currently, latest/edge ships with edk2 2025.02-8ubuntu3 and that works well to boot arm64 with SB enabled. I'm currently trying to bring the latest edk2 from resolute into the LXD snap (https://github.com/canonical/lxd-pkg-snap/pull/1119). This is when I noticed that arm64 secureboot regressed but was fixed by https://github.com/canonical/lxd-pkg- snap/pull/1119/changes/588212433dacc7b2551322d157bcb552897216bb which is essentially the diff suggested in the bug description here. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2145095 Title: Please reintroduce PcdUninstallMemAttrProtocol=TRUE for arm64 build To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/edk2/+bug/2145095/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
