Installing Ubuntu One to sync files, contacts and Tomboy Notes is quite straight-forward in Linux Mint 9 (which is built on Ubuntu) but there are a couple of caveats.
You can install Ubuntu One by simply typing this into the Terminal:
sudo apt-get update sudo apt-get install ubuntuone-client-gnome
The problem however appears when you try to install the plugin (Bindwood) to sync Firefox bookmarks in the Ubuntu One application. Not only does it not work – it also messes up an entry in your /etc/apt/sources.list. This means that you will get an error when you run update manager (and you will have an icon in the taskbar that reminds you of this all the time).
To avoid this problem you can install the Bindwood plugin manually as follows:
sudo apt-get install xul-ext-bindwood
If you need to correct your /etc/apt/sources.list this can be done as follows, In the Terminal type:
sudo gedit /etc/apt/sources.list
Look for the deb http://packages.linuxmint.com/ isadora main upstream import universe entry and remove “universe” from the end of it so that it looks like this:
deb http://packages.linuxmint.com/ isadora main upstream import
Save the file and close the file editor and then update your repositories again:
sudo apt-get update
