Benjamin, Seeing that message is normal when you have new virtual interfaces such as 'vboxnet0' from VirtualBox, see comment #266.
Have you run updates since your installation of Karmic? There was one know problem with Ubuntu One and synchronization was disabled for the release. You would see an icon with two arrows circling an exclamation mark if it is the case, along with a popup notification if it is the case. This should be fixed now. Otherwise, consider opening a new bug, since as you say other network related things are working. Don't forget to tell us what new bug number it is :) Thanks, -- [MASTER] [WORKAROUND] "Offline Mode" feature fails to detect proper online state for networks that are managed outside of network manager. https://bugs.launchpad.net/bugs/191889 You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is a direct subscriber. -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
