Dropbox installation on Ubuntu 14.04.2 LTS with problem solving

Somehow Dropbox does not want to work for me on laptops...

so,

1. ) install nautilus-dropbox from apt

sudo apt-get install nautilus-dropbox

2.) solve permission issue (if present):
find out where dropbox launcher is stored:
which dropbox
edit the path you got from which command (for me it is /usr/bin/dropbox )
sudo gedit /usr/bin/dropbox
find the line causing the permission issue (looking at the wrong place for dropbox):

PARENT_DIR = os.path.expanduser("/var/lib/dropbox")

change it to your home directory (the daemon will be installed here)

PARENT_DIR = os.path.expanduser("~")
save the file.

3.) install dropbox from dropbox official site through ppa repository
sudo sh -c 'echo "deb http://linux.dropbox.com/ubuntu/ trusty main" >> /etc/apt/sources.list.d/dropbox.list' sudo apt-key adv --keyserver pgp.mit.edu --recv-keys 5044912E sudo apt-get update sudo apt-get install dropbox

4.) restart nautilus
nautilus --quit

5.) start dropbox with daemon install
dropbox start -i

6.) add notification area to gnome-panel (if not present):
Super+Alt+RightClick panel > Add to panel... > Notification Area

Hopefully, everything is working now without any kind of unexpected messages.
