Comment 2 for bug 516935

johan,
Thank you for taking the time to report this bug and helping to make Ubuntu better. Sorry you are having problems with Ubuntu One. It looks like you are still running Ubuntu One from Jaunty. To fix this open a Terminal (Applications > Accesories > Terminal) and run the following:

sudo apt-get update && sudo apt-get upgrade

If you have not ran an update since you moved to Karmic you might have quite a few other packages that will update as well. After the update you will need to quit and then restart your Ubuntu One Client.

This particular bug has already been reported and is a duplicate of bug 462828, so it is being marked as such. Please look at the other bug report to see if there is any missing information that you can provide, or to see if there is a workaround for the bug. Additionally, any further discussion regarding the bug should occur in the other report. Feel free to continue to report any other bugs you may find.

thank you,
