As a wild guess, make sure the user that you're running the build as is in the "fuse" group. This is needed for disorderfs. If you don't want to do that, give --vary=-fileordering to reprotest. (This is actually already documented in the README / man page, and disorderfs IIRC should output an error message but that part is cut out of your log).

Otherwise, I'm out of ideas. You need to tell me exactly how to reproduce this issue, including how you created the chroot - otherwise I can't make any progress. I can't possibly guess why tail(1) shouldn't be able to read debian/changelog, apart from the "fuse" issue I just mentioned.

(I don't have NOPASSWD in my sudoers file either.)
