unable to perform lint, cause of errors

[advancedwebdeveloper]

Hi.
I was trying to build your package, since I was curious how good Golang fits for developing Ops infrastructure tools.
I am using gollvm

I tried to

$make lint

and got

I am working on Ubuntu 20.04.1 x86_64 and you can take my "release" build, from here, to reproduce this bug.
