What is the reason, how to solve it?

Answer 1

This repo uses Go modules feature and installation instructions clearly state it requires Go 1.13 or higher:

0. Install Go 1.13 or higher

From error messages it seems you have Go 1.10 which doesn't support modules (and likely also other features this repo depends on).

This error is caused by fact that prior modules support was added to Go in version 1.11; go tool was always looking up modules in $GOROOT and $GOPATH locations - and in your case it can't find them there.

Install Go 1.13 or higher to make the installation guide work. You can find recent enough packages in backport PPA or install latest from official tarball available here .
