Hi, We previously attempted to turn on zboot with zstd on arm64 but that had a regression with qemu -kernel unable to boot it; and kexec unable to load it either.
However qemu has gained support for zboot with gzip compression; and there are patches for kexec too. Thus it should be safe to turn on zboot gzip, install it as vmlinuz without anybody noticing. It should also just work for Ubuntu core. Signing should work too, as it checks if vmlinuz is compressed and decompresses only when needed for signing. Please turn on zboot gzip. Please consider to sru that (as long as kexec tools supports it). -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2098111 Title: arm64: kernel image cannot be booted in UEFI despite EFI stub and ZBOOT To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/2098111/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
