I am trying to install Dropbox to my Xubuntu 14.04 and I found two ways to do this from their official site and I am just wondering which one is the best.
Option -1 : https://www.dropbox.com/install?os=lnx
I tried to follow the option 2 method but the command line result is the following
X@Y:~$ sudo apt-key adv --keyserver pgp.mit.edu --recv-keys 5044912E
Executing: gpg --ignore-time-conflict --no-options --no-default-keyring --homedir /tmp/tmp.8QwEMoXWMR --no-auto-check-trustdb --trust-model always --keyring /etc/apt/trusted.gpg --primary-keyring /etc/apt/trusted.gpg --keyring /etc/apt/trusted.gpg.d/chromium-daily-ppa.gpg --keyring /etc/apt/trusted.gpg.d/deluge-team-ppa.gpg --keyring /etc/apt/trusted.gpg.d/hydr0g3n-qbittorrent-stable.gpg --keyring /etc/apt/trusted.gpg.d/otto-kesselgulasch-gimp.gpg --keyring /etc/apt/trusted.gpg.d/pidgin-developers-ppa.gpg --keyring /etc/apt/trusted.gpg.d/ubuntu-wine-ppa.gpg --keyring /etc/apt/trusted.gpg.d/videolan-stable-daily.gpg --keyserver pgp.mit.edu --recv-keys 5044912E
gpg: requesting key 5044912E from hkp server pgp.mit.edu
gpgkeys: key 5044912E can't be retrieved
gpg: no valid OpenPGP data found.
gpg: Total number processed: 0
So nothing just happened here and i didn't go further with Option 2.
