/bin/sh: 1: go: not found

The go binary is not in your PATH.

@wpaulino why isn't it? I followed the instructions exactly as written in this repo.

[Roasbeef]

Check your PATH, you may have installed Go in a slightly different directory. Also you can do which go to find where it's pointing to atm.

As @Roasbeef suggested, use the following command to check your path setting:

echo $GOPATH  # this should point to your workspace
echo $PATH
go version  # check go version, it should be at least 1.12
gedit ~/.profile  # to modify PATH
source ~/.profile  # to activate changes

I also use Ubuntu so I know the struggle when configuring the Go. If all the above not working, I suggest you remove and install Go again, directly installing tar package. Installation guide here. Following is tested and worked perfectly fine on my Ubuntu 18.04

which go  # output like /usr/local/go/bin/go
rm -rvf /usr/local/go/
sudo apt-get remove golang-go
sudo apt-get remove --auto-remove golang-go
