I have a desktop PC running Ubuntu 10.04.4 LTS with Xfce and a laptop running Ubuntu 12.04.2 LTS with Gnome. They had both been sharing the same files with Ubuntu One without problems for ages which allowed me to edit the same files on either machine and the latest changes made were always applied. However, some while back the PC stopped connecting to Ubuntu One (without showing any errors), though I wasn't aware of changing anything. The laptop still connects and syncs fine. The log files revealed nothing so I'm trying to remove the Ubuntu One software from the PC as per this link but I do not have the entry "Passwords and Encryption Keys" in the Accessories menu referenced in step 6. Ultimately I want to try and reinstall Ubuntu One. Interestingly the laptop is also missing the exact same menu entry so I guess I am the common link.... Any ideas, anyone?
