Also, > using EFI+btrfs boot volume. No LVM used, just GPT on NVMe.
Yes, this change was introduced to address the problem as seen on LVM- backed /boot/grub, but that is certainly not the only configuration for which GRUB has read support but lacks write support. The fix is generic to all such filesystems that are read-only in GRUB, and that is by design. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1814403 Title: Latest update causes 30 sec. menu delay timeout To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/grub2/+bug/1814403/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
