Next, run the Dropbox daemon from the newly created .dropbox-dist folder.

~/.dropbox-dist/dropboxd
If you’re running Dropbox on your server for the first time, you’ll be asked to copy and paste a link in a working browser to create a new account or add your server to an existing account. Once you’ve done this, your Dropbox folder will be created in your home directory. Download this Python script to control Dropbox from the command line. For easy access, put a symlink to the script anywhere in your PATH.

% chmod 700 dropbox.py
% sudo mv dropbox.py /usr/local/bin/dropbox

# 起動は
% dropbox start

# 状況確認
% dropbox status

dropbox stop
dropbox status # Should report "not running"
rm -rf ~/.dropbox-dist
rm -rf /var/lib/dropbox
rm -rf ~/.dropbox*
sudo apt-get remove nautilus-dropbox
sudo apt-get remove dropbox
rm /etc/apt/source.d/dropbox
