Say you use GitLab for hosting code and you use their subgroup/team thingy to organize people (or projects). How do you get it work with Go modules (privately!)
Say the thing you want to import is at
1gitlab.com/my-team/my-subteam/my-subsubteam/repo-a
with the following code
1-- go.mod --
2module gitlab.com/my-team/my-subteam/my-subsubteam/repo-a
3
4go 1.16
5
6-- a.go --
7package a
8
9var A = "A"
So, like all private code,
set the GOPRIVATE environment variable so go doesn't reach out to a proxy
1# for this session or persist in shell startup files
2export GOPRIVATE=gitlab.com/my-team
3
4# or persist in Go config file (go env GOENV)
5go env -w GOPRIVATE=gitlab.com/my-team
Setup git to clone using ssh,
go clones using https but you need a way to authenticate it.
# through cli
git config --global url."git@gitlab.com:".insteadOf "https://gitlab.com/"
# or in ~/.gitconfig or $XDG_CONFIG_HOME/git/config
[url "git@gitlab.com:"]
insteadOf = "https://gitlab.com/"
And obtain an access token from gitlab and put it in ~/.netrc,
so the go get can find the correct repo root
important: the access token needs read_api, not just read_repository
machine gitlab.com
login seankhliao
password _FREdNJyBnFwZDn9Gj48
And you're all set

You haven't setup noninteractive git clones, see above section for gitconfig.
You should be able to git clone https://gitlab.com/you/private/repo without any further input (importantly over https)

You haven't set GOPRIVATE and go is asking the public sumdb for the checksum,
which it can't access, (private code, remember?).
