This was fixed by changing ubuntuone.com certificate to a non-wildcard one.
** Description changed: New lucid accounts cannot register or add a new machine. At the moment ubuntuone-preferences shows an error message: Authorization Error [Errno socket error] SSL hostname validation failed This is happening because ubuntuone.com (which is referenced from lucid clients) has subject field of SSL certificate set to *.ubuntuone.com and the monkey-patched SSL verification checks for subject field only. ubuntuone.com is present in subjectAltName but it is not being checked. - WORKAROUND: - - 1. Download oauth_urls file from launchpad: https://bugs.launchpad.net - /ubuntuone-client/+bug/1081144/+attachment/3440368/+files/oauth_urls - - 2. Put the file e.g. in /tmp folder - - 3. Open terminal (Alt+F2, gnome-terminal or Ctrl+Alt+T in default GNOME - environment) - - 3. Run the following: - $ sudo cp /tmp/oauth_urls /etc/xdg/ubuntuone - - This will prompt you for a password to your account. - - 5. Run the following to shut down existing ubuntuone-login process that has cached old configuration: - $ pkill ubuntuone-login - - 6. Start ubuntuone-preferences again. + FIXED by changing the certificate on the server side. ** Changed in: ubuntuone-client (Ubuntu) Status: Confirmed => Won't Fix ** Changed in: ubuntuone-client Status: New => Won't Fix -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1081144 Title: [lucid] ubuntuone-preferences: SSL hostname validation failed To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntuone-client/+bug/1081144/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
