The above should get you to a useable page. Download the USB version of the .deb package. I stored mine in the /root but had to copy it to the /tmp directory and install it from there. I installed the .deb package after the apt upgrade process, then rebooted. There may be a more recent version of the package. If I find it, I'll post a link
Hope this helps, let me know if you run into trouble.
