How to properly install Nuclei

Installation step by step avoiding pitfalls

You might think that installing Go and nuclei is simple. That's what I thought.

I had several instances of Nuclei running in different servers. I wanted to use a machine with low load to do some scans. An Ubuntu 18.04 Linux instance and it took me couple of hours to get it running.

Let me explain you why. There are two things that can fail (and will, especially if you are in a hurry or need to do something important, that's Murphy's law, it's science).

Update: If you use Ubuntu 20.04 the installation process is much simpler and you don’t need to do the next manual steps.

Using an old Go version might really destroy your ego

So, you need to install Go. What do you do?
