Key server shuts down when installing docker on Ubuntu 14.04

I am trying to install docker on Ubuntu 14.04, however I cannot go beyond the first document documented here: https://docs.docker.com/engine/installation/ubuntulinux/

$ sudo apt-key adv --keyserver hkp://p80.pool.sks-keyservers.net:80 --recv-keys 58118E89F3A912897C070ADBF76221572C52609D Executing: gpg --ignore-time-conflict --no-options --no-default-keyring --homedir /tmp/tmp.VB8X4gv8Ty --no-auto-check-trustdb --trust-model always --keyring /etc/apt/trusted.gpg --primary-keyring /etc/apt/trusted.gpg --keyserver hkp://p80.pool.sks-keyservers.net:80 --recv-keys 58118E89F3A912897C070ADBF76221572C52609D gpg: requesting key 2C52609D from hkp server p80.pool.sks-keyservers.net gpg: keyserver timed out gpg: keyserver receive failed: keyserver error

The key server shuts down a couple of minutes after executing this command. Anyone else run into this issue? I saw several messages about blocking port blocking 11371. But I already use port 80, so this should not be a problem.

What can I do to manually update keys on Ubuntu if the preferred way to retrieve it from a key server using apt-key does not work?

Try this key server "hkp: //keyserver.ubuntu.com: 80"

sudo apt-key adv --keyserver hkp: //keyserver.ubuntu.com: 80 --recv-keys 58118E89F3A912897C070ADBF76221572C52609D

It worked for me.

At the time of this writing, http://www.downforeveryoneorjustme.com/p80.pool.sks-keyservers.net reports p80.pool.sks-keyservers.net as dropping.

This will explain the error message.

Updating in an hour the message p80.pool.sks-keyservers.net will appear again.

OP rkrishnan confirms in comments to install dockers using apt-get install docker-engine

Install docker with apt-get install docker-engine and it worked for me. I wonder why this is not standard documentation in docker docs!
