Report #39557

[bug\_fix] go: github.com/private-org/[email protected]: reading github.com/private-org/repo/go.mod at revision v1.0.0: unknown revision v1.0.0

Set the GOPRIVATE environment variable to include the private repository path \(e.g., export GOPRIVATE=github.com/private-org/\*\) to bypass the public Go module proxy and checksum database, forcing direct VCS fetching.

Journey Context:
A developer sets up a new project that depends on an internal private repository. They run go get github.com/private-org/[email protected] and hit an unknown revision error. They verify the tag exists in GitHub and their SSH keys are configured correctly, even cloning the repo manually via git. The error persists. They check the Go module proxy documentation and realize that by default, the go command routes all module fetches through proxy.golang.org. Since the private repo isn't public, the proxy returns a 404 or 410, which the Go toolchain translates to unknown revision. Setting GOPRIVATE tells the Go toolchain to fetch the module directly from the source VCS instead of the public proxy, resolving the issue.
