Comment 6 for bug 624445

dbroomex,
The fixes for Maverick, that have been causing the most common connection issues, have made it to the main repository. Can you make sure your system is up to date and let us know if this bug is still effecting you.

If you are still having trouble connecting you may need to delete your Ubuntu One Token from Seahorse an re-add your computer with the newer client. Just in case, I have included those steps below.

   1. Quit the Ubuntu One Preferences (if open)
   2. Open Applications->Accessories->Passwords and Encryption Keys
   3. Click on the arrow next to "Passwords"
   4. Right-click on the Ubuntu One token and select "Delete"
   5. Go to https://one.ubuntu.com/account/machines/
   6. Click on the checkbox next to your computer
   7. Click the "Remove selected computers" button
   8. Open System -->Preferences-->Ubuntu One
   9. a web page should open, prompting you to add your computer to your Ubuntu One account
  10. Add your computer

Thank You,
