I am a bit of a newbie at this but have been running Kubuntu from ubuntu 14.04 which runs fine, I have been trying to get the dropbox icon to appear in the sys tray (it runs in the background ok) but have hit a wall.

I get the following dialogue from the terminal:

W: GPG error: http://linux.dropbox.com trusty Release: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY FC918B335044912E

the public key is not available?


Dropbox’s repository key

sudo apt-key adv --keyserver pgp.mit.edu --recv-keys 5044912E

Dropbox’s repository

sudo add-apt-repository "deb http://linux.dropbox.com/ubuntu $(lsb_release -sc) main"

Update and Install

sudo apt-get update && sudo apt-get install 

Run dropbox


Follow instructions....
