I find Ubuntu One too intrusive. For example, there is a cloud icon in my top panel that has an attached Ubuntu One menu. One item on the menu is to turn Ubuntu One off. When I do this it turns itself back on again. I don't like this lack of control, particularly where network access is concerned. Does anybody have explicit instructions in removing this application? I am seriously considering changing distros if I can't fully control Ubuntu One.
Found the relevant bits:-
Run the following in a terminal session:
killall ubuntuone-login ubuntuone-preferences ubuntuone-syncdaemon
sudo rm -rf ~/.local/share/ubuntuone
rm -rf ~/.cache/ubuntuone
rm -rf ~/.config/ubuntuone
If you have UDFs, rename the respective folders. E.g. if you were syncing Documents folders, rename it to Documents_old.
mv ~/Ubuntu\ One/ ~/UbuntuOne_old/``
Delete Ubuntu One token:
Open the Dash by clicking the Ubuntu Logo in the upper left corner. Type: Passw . Click Passwords and Encryption Keys. Go to the Passwords tab, click to expand the Password folder, delete the entry called "Ubuntu One". Note that this may not be loaded if you have not subscribed.
In a terminal session run:
sudo apt-get purge ubuntuone-client python-ubuntuone-storage*
