I went to www.dropbox.com/downloading to download and install the latest 64-bit Ubuntu .deb file (dropbox_2015.10.28_amd64.deb ) that is provided on the page. I installed it using the command:
orschiro@x230:~$ sudo dpkg -i dropbox_2015.10.28_amd64.deb
After launching Dropbox and providing my account credentials, I am then presented with the following screen. Where am I supposed to get the latest version of Dropbox from if not on their official website?
