I reported this Fedora bug then: > https://bugzilla.redhat.com/show_bug.cgi?id=3D1440429 It would be useful to know which feature(s) that Fedora 25 enabled that Ubuntu 16.04 didn't understand. You could use something like: dumpe2fs -h /dev/XXX | grep -i feature under Ubuntu. Typically, the code shouldn't be enabling any feature on the filesystem without an explicit request from the admin. Also, the "failed to mount" case should print something to the console logs about an unsupported feature, which would help isolate the problem.
