Felipe, could you please try running $ sudo update-ca-certificates on your desktop and try to restart the application.
Additionally, could you please archive the contents of /etc/ssl/certs and attach that to this bug report. Is UbuntuOne the only application that is failing with SSL errors? Could you please try running wget as $ wget https://one.ubuntu.com/ -o /tmp/test-460851 And see whether it complains about the certificate? ** Changed in: ubuntuone-client (Ubuntu) Assignee: Rodney Dawes (dobey) => Roman Yepishev (rye) ** Changed in: ubuntuone-client (Ubuntu) Status: Confirmed => Incomplete -- [Errno socket error] [Errno 1] _ssl.c:480: error:14090086:SSL routines:SSL3_GET_SERVER_CERTIFICATE:certificate verify failed https://bugs.launchpad.net/bugs/460851 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
