Error running hugo server

[mcx]

Hi everyone,

I keep on getting this error whenever I run hugo server or hugo mod clean
Error: we found a go.mod file in your project, but you need to install Go to use it. See https://golang.org/dl/.: module "github.com/wowchemy/wowchemy-hugo-modules/netlify-cms-academic" not found; either add it as a Hugo Module or store it in "/$USER/academic-starter/themes".: module does not exist

The command hugo mod get -u ./... works but the above error still persists. Installing Go with the default instructions on Ubuntu 18.04 did nothing either.

This is my first experience with Hugo so any help would be most welcomed.
Thank you.
