Newer releases of Ubuntu can always start making use of new file system feature flags. Looking at all currently supported releases (whether standard or ESM), we have never SRUed e2fsprogs before, it only ever received security updates, so I'd be inclined to not do a backport here either and resolve that in the snap side of things.
Generally for recovery purposes you will be booting an image with an equal or newer version of Ubuntu. Regarding Dimitri's comment about new kernel feature support in 5.15, that doesn't seem related to this issue, and I'm not sure we should be changing feature flag in a stable release anyhow. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to e2fsprogs in Ubuntu. https://bugs.launchpad.net/bugs/2025339 Title: FDE image fails to run e2fsck Status in e2fsprogs package in Ubuntu: Confirmed Status in e2fsprogs source package in Jammy: Confirmed Bug description: After installation of the FDE image, the system fails to boot due to e2fsck failing with: Jun 21 12:48:19 ubuntu systemd-fsck[268]: /dev/vda2 has unsupported feature(s): FEATURE_C12 ---- this means that Jammy fsck fails against mantic created ext4 which is not great Seems this is orphan_file feature / orphan_present Also need to check if grub2 supports this as it is RO_INCOMPAT feature.
