title: I can't install golang and godoc at the same time on Ubuntu
body: <p>I installed golang using <code>sudo apt-get install golang</code>. Then I can use the <code>go</code> command. But there is no godoc command. I found online I can use <code>sudo apt-get install golang-go.tools</code> to install godoc. When I do that I can use the <code>godoc</code> command but the <code>go</code> command doesn't work anymore. How can I make them both work on the same time?</p>
