If you’ve never tried Ubuntu One, then the first two steps will be unnecessary, but they don’t take long so it might be safer to go through them all anyway.
To start, we need to make sure that Ubuntu One isn’t running. Open the System Monitor, in System > Administration > System Monitor.
In the Processes tab, look for anything that starts with “ubuntone”. Select them, and click End Process.
Next, we’ll get rid of the stored authentication token for Ubuntu One. Click on Applications > Accessories > Passwords and Encryption Keys.
If a token for UbuntuOne exists, right-click on it and select Delete.
Now we can remove all of the folders that Ubuntu One uses. Open up a terminal window (Applications > Accessories > Terminal) and enter the following commands:
The backslash in the last command is there because the folder name has a space in it.
Finally, we can remove all of the packages related to Ubuntu One.
In the terminal window, type in:
Confirm the removal of all of the packages, and you’re done!
If you ever want to reinstall Ubuntu One, you can follow the instructions on Ubuntu One’s Launchpad site.
