One time solution:

dropbox stop
env XDG_CURRENT_DESKTOP=Unity dropbox start -i

Follow SOURCE LINK above for complete solution:

cp ~/.config/autostart/dropbox.desktop ~/.config/autostart/start_dropbox.desktop
sed -i 's/^Exec=.*/Exec=env XDG_CURRENT_DESKTOP=Unity dropbox start -i/' ~/.config/autostart/start_dropbox.desktop
dropbox stop
env XDG_CURRENT_DESKTOP=Unity dropbox start -i
**DROPBOX > PREFERENCES > disable "Start Dropbox on system startup"
mkdir -p ~/.local/share/applications/
cp /usr/share/applications/dropbox.desktop ~/.local/share/applications/
sed -i 's/^Exec=.*/Exec=env XDG_CURRENT_DESKTOP=Unity dropbox start -i/' ~/.local/share/applications/dropbox.desktop
