# Error: Failed to download module: could not download module "my_module" (main.tf:1) source code from "git::https://github.com/myorg/terraform-modules.git//networking?ref=v1.0": error downloading 'https://github.com/myorg/terraform-modules.git': git clone failed: remote: Repository not found.

- **ID:** `terraform/module-source-not-found-git`
- **Domain:** terraform
- **Category:** install_error
- **Verification:** ai_generated
- **Fix Rate:** 80%

## Root Cause

The Git repository specified in the module source does not exist, is private without proper authentication, or the URL is incorrect (e.g., typo, wrong org name).

## Version Compatibility

| Version | Status | Introduced | Deprecated |
|---------|--------|------------|------------|
| Terraform v1.5 | active | — | — |
| Terraform v1.6 | active | — | — |
| Terraform v1.7 | active | — | — |
| Git v2.30+ | active | — | — |

## Workarounds

1. **Verify the repository URL is correct by manually cloning it: 'git clone https://github.com/myorg/terraform-modules.git'. If it fails, check for typos or access permissions. For private repos, use a personal access token: 'git clone https://<token>@github.com/myorg/terraform-modules.git' or configure git credentials. Then run 'terraform init' again.** (85% success)

2. **If the repo is private, set up Git credentials via environment variable: 'export GIT_TERMINAL_PROMPT=0' and 'export GIT_ASKPASS=/path/to/helper' or use SSH authentication. Example: 'export GIT_SSH_COMMAND="ssh -i ~/.ssh/id_rsa -o StrictHostKeyChecking=accept-new"' then 'terraform init'.** (75% success)

## Dead Ends

- **** — In non-interactive CI/CD environments, there is no terminal for password input. Also, Git credentials should be configured via SSH keys or tokens, not interactive prompts. (90% fail)
- **** — SSH access requires proper SSH keys configured in the environment. Without keys, SSH also fails with 'Permission denied'. (85% fail)
- **** — The -from-module flag is for migrating state, not for fixing module download errors. It does not affect source URL resolution. (95% fail)
