Report #11863

[bug\_fix] go: github.com/user/[email protected]: reading github.com/user/private-repo/go.mod at revision v1.0.0: unrecognized import path "github.com/user/private-repo": https fetch: Get "https://github.com/user/private-repo?go-get=1": status code 404

Set the GOPRIVATE environment variable to include the private repository path \(e.g., export GOPRIVATE=github.com/user/private-repo\). This instructs the Go toolchain to bypass the public proxy and checksum database and fetch the module directly from the source repository using the configured VCS credentials.

Journey Context:
A developer sets up a CI pipeline for a project that depends on an internal private repository. The build fails with a 404 or unrecognized import path error. The developer verifies that the CI runner's Git credentials are correct and can manually clone the private repo via SSH. They spend hours debugging Git configurations, netrc files, and SSH keys, wondering why go mod download fails while git clone succeeds. The breakthrough comes when they realize the Go toolchain defaults to routing all module fetches through proxy.golang.org. Since the proxy cannot access private repositories, it returns a 404. Setting GOPRIVATE tells the Go toolchain to bypass the public proxy and fetch directly from GitHub, leveraging the already-working VCS credentials.
