The issue is with the Go package you installed.Which version you have installed? The ideal way to install the latest Go is from here.Go

And if your using ubuntu don't go with the apt installation.

First remove apt installed go

  • $ sudo apt-get remove go

  • Download the tar file for linux from the site https://golang.org/dl/ 450

  • Execute the command $ sudo tar -C /usr/local -xzf

As previous answer suggest: previous go lang version causes this issue

so first remove previous go : (suggested answers doesn't remove go so i added it here)

  1. sudo apt-get remove golang-go
  2. sudo apt-get remove --auto-remove golang-go
  3. sudo apt-get purge golang-go

download latest go and add go/bin path to environment variable

I agree, this looks like a Go version issue. Fabric 2.0 has a prerequisite of Go version 1.13

Before 1.11 Go did not have the mod command(I think). So if you did install Go version 1.13, maybe you didn't remove the older version and its still pointing to the older version of Go.

Do a

peer version

in the same terminal where you ran the ./network.sh deployCC command and check the version of Golang that was being used. If you do see 1.10 being used then, you need to upgrade Golang.

Take a look at the install instructions at https://golang.org/doc/install and follow the uninstall steps for the old version and the install steps for the new version and also ensure you have the Path Variables set for Fabric
