Got something like:

$ go get github.com/foo/bar@latest
go: downloading github.com/foo/bar v0.21.0
go: downloading github.com/foo/bar v0.0.0-20221202205032-05c20c95981f

	Confirm the import path was entered correctly.
	If this is a private repository, see https://golang.org/doc/faq#git_https for additional information.

This is because you’ve set up SSH to work with git but go get uses HTTPS. the recommended link is a good starting point, but luck has it that you’ll probably have to set GOPRIVATE. That one I keep forgetting about, so this is your friendly reminder :)

TLDR;

First:

git config — global url."ssh://git@github.com/".insteadOf "https://github.com/"

Then:

go env -w GOPRIVATE=github.com/<company>
