After upgrading to Ubuntu 10.4 LTS (Lucid Lynx) I was having a problem with my Ubuntu One profile. Clicking the Me Menu at the top right corner and choosing Ubuntu One showed an empty profile (unknown name, email, etc.). I was able to log in to my Ubuntu One website and thinking the problem was related to duplicate machines, I removed all listed machines, thinking I could simply add my machine afterwards. However, this was easier said than done. The Ubuntu One instructions told me to click the “Add Your Computer” button, which was nowhere to be found. Luckily, the Ubuntu One FAQ had the solution:

  1. Close the Ubuntu One Preferences application window (if it’s already open).
  2. Open your Terminal (located in Applications >> Accessories) and type the following:
u1sdtool -q; killall ubuntuone-login; u1sdtool -c

This should force a web browser to open and and you should be able to see a button for adding a computer to Ubuntu One. After adding my computer, my problem was fixed, and the Ubuntu One application preferences on the Me Menu showed correct user details. Apparently the above is a temporary measure and the Ubuntu One team will implement a more permanent fix for this problem soon.
