Description of problem: Déjà Dup Backup Tool requires at least version 0.6.23 of duplicity, but only found version 0.6.00 rpm -q deja-dup deja-dup-32.0-3.fc21.x86_64 rpm -q duplicity duplicity-0.6.25-1.fc21.x86_64
This is due to the deprecation warning in the --version output. If it's trivial to patch out I will, otherwise I'll just upgrade to 0.7.01 which I've tested and works fine with deja-dup.
