I have got a problem because of the non-matching features, too: I formatted a new drive with ext4 under Ubuntu 16.10 and added it to the fstab of my precise and trusty installations.
These two LTS installations stop during the boot press giving me an error because e2fsck does not recognize the new features. (The problem does not occur for xenial.) As Norbert and Theodor above: e2fsprogs 1.43 should be backported to precise and trusty; especially now that the new features are enabled by default. In trusty, I am now using Daniel Mehrmann's PPA, which is offering a snapshot of e2fsck 1.43. Daniel Mehrmann's package does not build in precise because it seems to need a newer version of libc6. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1601997 Title: Ubuntu 16.10 installer sets metadata_csum option on ext4 partition which is incompatible with other LTS Ubuntu versions To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/e2fsprogs/+bug/1601997/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
