TFE: Getting a 404 error when trying to create a GPG key resource

Problem

When using the GPG Keys API to create a GPG key for a private provider, Terraform Enterprise may return a 404 not found error.

{
  "errors": [
    {
      "status": "404",
      "title": "not found"
    }
  ]
}

Prerequisites

• Terraform Enterprise versions prior to v202203-1.

Cause

The API endpoint for managing GPG keys, /api/registry/private/v2/gpg-keys, was introduced in Terraform Enterprise version v202203-1. In earlier versions, this endpoint does not exist, causing the API to return a 404 not found error when you attempt to use it.

Solution

To resolve this issue, you must upgrade Terraform Enterprise to version v202203-1 or a newer release. Support for private providers in the Private Registry was introduced in this version.

For a complete list of features and updates in this release, refer to the v202203-1 release notes.

Outcome

After upgrading Terraform Enterprise to version v202203-1 or newer, you can successfully use the GPG Keys API to add a key and publish a private provider to the Private Registry.
