SSLError: [Errno bad handshake] [('SSL routines', 'SSL3_GET_SERVER_CERTIFICATE', 'certificate verify failed')]

[Jorman Franzini]

Hi, I've some problem on duplicity run, my config is:
Using installed duplicity version 0.7.05, python 2.7.3, gpg 1.4.7 (Home: ~/.gnupg), awk 'GNU Awk 4.0.1', grep 'grep (GNU grep) 2.12', bash '3.2.54(1)-release (i686-unknown-linux-gnu)'.

And this's the log for the run:

Any idea?
