My current work around is to manually maintain the grub.cfg in /boot/grub. Using the version that was generated under 19.04, I have simply updated the kernel and initrd to reflect the new modules.
This still means that any package I install that needs to regenerate the grub.cfg will fail. So far it is only related to cleanup of the kernel and I expect the same will be true with the add of new kernels. Not ideal but I haven't found the root of the problem with the 10_linux_zfs script. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1848856 Title: Upgrade from 19.04 to 19.10 with zfs on root fails with grub syntax error To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/grub2/+bug/1848856/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
