I am seeing the same problem on non-mirrored root disk, using a simple LVM volume.
I am currently testing the upgrade from 22.04 to 24.04 using `do- release-upgrade -p`. For the test I deploy a machine with MAAS installing Ubuntu 22.04, then trying to upgrade to 24.04. Everything works except the error from grub-install, since it's trying to install to the LVM volume instead of the disk where the volume is located. At this point I can either purge the package grub-pc and then install it again. A simple `dpkg-reconfigure --force grub-pc` does not work, it shows all the questions EXCEPT the disk selection dialog. Or I can get the disk selection dialog back by setting: ``` echo 'grub-pc grub-pc/cloud_style_installation boolean false' | debconf-set-selections ``` I also tested running `dpkg-reconfigure grub-pc` before the upgrade and selected the correct disk. The upgrade afterward fails anyway with the same error, probably because cloud_style_installation does not get reset? Anyway, any idea why the default selection is the LVM volume instead of the disk on which the volume resides? Is it cloud-init or MAAS seeding cloud-init with the wrong value? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2060695 Title: 24.04 grub-pc cannot upgrade on mirrored software RAID root disk To manage notifications about this bug go to: https://bugs.launchpad.net/subiquity/+bug/2060695/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
