I did so. The computer gave me the following mistake (both root and normal user)
Starting Dropbox...Dropbox isn't running!
Done!
bash-4.2# Couldn't start Dropbox.
This is usually because of a permissions error. Storing your home folder on a network share can also cause an error.

I also created the folder Dropbox manually, but nothing changed.
