Following solution helped me:

sudo apt-get clean
cd /var/lib/apt
sudo mv lists lists.old
sudo mkdir -p lists/partial
sudo apt-get clean
sudo apt-get update

I am assuming Ubuntu 14.04 on a recent Droplet (considering apt-get is looking for trusty)… lsb_release -a will tell you your Ubuntu version.

Do you have ufw enabled? If so, disable ufw and try apt-get update again…if it works, you need to add outgoing rules for http(s) and dns like so ufw allow out 80 ufw allow out 443 ufw allow out 53 ufw enable

try apt-get update again…now it should work
