You don't need ext4dev.  ext4dev is old and, unless you've used it
before, there's no need to use it today.  I'm guessing that's giving you
that error (that's an old error).  It's easy to fix though (do a Google
search for the error).  But it should not even occur if you've never
used ext4dev, IIRC.
