Hey Simon, From MM: > Would you mind giving me the exact specs of what systems/configurations are > affected by this?
The exact changes are available to view on the streamline branch of git.launchpad.net/~ubuntu-core-dev/grub/+git/ubuntu in the top 5 commits. The oneline git log shows: a855df6c1 Streamlining: Drop support for LVM, RAID-5 and RAID-6 022b88968 Streamlining: Drop support for encrypted /boot 26122149b Streamlining: Drop support for rendering images ee8354a4e Streamlining: Drop Apple partition table support 883394e14 Streamlining: Drop btrfs, hfs+, xfs, zfs FS support As for what systems are affected by this: any system using `Apple partition table, btrfs, hfs+, xfs, zfs` as the /boot partition format will have an inaccesible `grub.cfg` and so will not be bootable if these changes come into effect. Anyone with an encrypted `/boot` will have the same issue, as well as anyone booting off a raid partition using raid-5 or raid-6. Please note that this does not affect `/home` or `/` partition support from Ubuntu. The change should then warn/deny upgrade if the `/boot` partition format matches any of these. I am not sure of the impact of the image changes. I assume they simply just don't load the images, but I would need to check. Perhaps if the grub.cfg contains a .jpg or .png line, warn/deny should be done then too. Hopefully ~juliank can elaborate further. I will dig a bit deeper and report any further learnings Best, Artie -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2170211 Title: Systems using niche /boot configurations won't be able to upgrade from 26.10 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ubuntu-release-upgrader/+bug/2170211/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
