dnf fails if stdin (fd 0) is not open: AttributeError: 'NoneType' object has no attribute 'isatty'

Running `dnf -y update --best` when stdin (fd 0) is not open gives this error: [. . .] Delta RPMs reduced 93.7 MB of updates to 54.7 MB (41.1% saved) warning: /var/cache/dnf/updates-e042e478e0621ea6/packages/kernel-4.2.5-300.fc23.x86_64.rpm: Header V3 RSA/SHA256 Signature, key ID 34ec9cba: NOKEY The downloaded packages were saved in cache till the next successful transaction. You can remove cached packages by executing 'dnf clean packages'.

I should say that the reason that stdin is not connected to anything is a bug in libguestfs (see bug 1280029). But I still think this is also a bug in dnf because it should do something like: if (sys.stdin and not sys.stdin.isatty ()) and not ay: [etc]
Looks like James already filed the dnf bug. *** This bug has been marked as a duplicate of bug 1278382 ***
