Please advice.

As you have pointed out in your comment, on your system echo $GOPATH and echo $GOROOT produce empty output. This indicates an incomplete installation of go. Now, assuming you have installed the go toolchain via the downloads on the website or better yet, gvm, the all there is left to do is make the environment persist the changes across terminal sessions.

Adding

export GOPATH=*your path to GOPATH*
export GOROOT=*path to your go installation*

to your ~/.bashrc, restarting terminal session, restarting VSCode and reattempting to install the tools should do the trick.
