Digging a little deeper, I found out that the reason, at least for me, was a missing NetworkManager Applet.
I had my network configured manually and uninstalled the Applet. When I reinstalled it, I could subscribe to Ubuntu One. I left my manual configuration untouched and the Applet always shows a little white cross in a red square. I seems that it doesn't need to work properly, but it is enough if it is simply there, I can also confirm that it works with Chromium as default browser. The problem is resolved for me. -- No "Add this computer" Website https://bugs.launchpad.net/bugs/464802 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
