golang framework gin problems when running govendor fetch

I'm trying the next gin that is a go framework

link

The installation process takes the following steps:

Go get govendor

$ go get github.com/kardianos/govendor

Create your project folder and cd inside

$ mkdir -p $GOPATH/src/github.com/myusername/project && cd "$_"

Vendor init your project and add gin

$ govendor init

But the problem is that when executing the following instruction:

govendor fetch github.com/gin-gonic/[email protected]

I get the following error in the terminal:

# cd /home/usuario/go/.cache/govendor/github.com/gin-gonic/gin; git fetch
fatal: unable to access 'https://github.com/gin-gonic/gin/': gnutls_handshake() failed: Handshake failed

Someone can tell me what I am missing or what I am doing wrong

the go version I'm using is:

go version go1.10.1 linux / amd64
