from Terminal
wget https://www.dropbox.com/download?dl=packages/debian/nautilus-dropbox_0.7.1_i386.deb -o nautilus.deb
next install the debian package, and grab any dependencies needed with apt-get
sudo dpkg -i nautilus.deb
sudo apt-get -f install
You will also need python-gpgme for the daemon
sudo aptitude install python-gpgme
If needed, now install the daemon
dropbox start -i
Do this again and you’ll be given a URL to authorize your machine with an account, afterwards there will be a Dropbox directory in your Home directory syncing with your account.
Final thing linux will complain about being unable to monitor the entire dropbox hierarchy, to fix this do
echo 100000 | sudo tee /proc/sys/fs/inotify/max_user_watches
