golang-github-pkg-errors-dev binary package in Ubuntu Focal amd64

 Package errors provides simple error handling primitives for the Go
 programming language.
 .
 The traditional error handling idiom in Go results in error reports without
 context or debugging information.
 .
 The errors package allows programmers to add context to the failure path in
 their code in a way that does not destroy the original value of the error.
