I solved or worked around the problem using this link: https://wiki.ubuntu.com/UbuntuOne/Bugs
this section: ROOT_MISMATCH in syncdaemon.log - This normally indicates that there may be two Ubuntu One accounts, one in the local cache and another setup in the keyring. This happens if the user installed Ubuntu One with one account and then sets up the computer again with a different account (but all the old Ubuntu One files in ~/.local/share/ubuntuone are still there under the old account). Working around this: Open Applications->Accessories->Terminal and run: u1sdtool -q; killall ubuntuone-login ubuntuone-preferences; sudo rm -rf ~/.local/share/ubuntuone rm -rf ~/.cache/ubuntuone rm -rf ~/.config/ubuntuone mv ~/Ubuntu\ One/ ~/Ubuntu\ One_old/ Open Applications->Accessories->Passwords and Encryption Keys, go to the Passwords tab, delete the Ubuntu One and Desktopcouch tokens by right-clicking on them and selecting "Delete" Back in a terminal session, run: u1sdtool -q; killall ubuntuone-login; u1sdtool -c -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/674876 Title: Nautilus keeps opening when ubuntu one plugin is installed -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
