After searching, I found that dbus was the problem. These 3 packages are upgraded after installation : dbus,dbus-x11,libdbus-1-3 from 1.6.8-1ubuntu6 to 1.6.8-1ubuntu6.1.
I've pinned these three packages to their original version and do the upgrade... And It works, users can connect, so the problem comes form dbus ! (I'll change affects consequently). ** No longer affects: ubuntu ** Project changed: policykit => dbus -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1207206 Title: rtkit-daemon warning policykit call failed did not receive a reply To manage notifications about this bug go to: https://bugs.launchpad.net/dbus/+bug/1207206/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
