# go: example.com/module@v1.0.0 is retracted by the module author; run 'go mod tidy' to update

- **ID:** `go/go-mod-tidy-fails-on-retracted`
- **Domain:** go
- **Category:** build_error
- **Verification:** ai_generated
- **Fix Rate:** 80%

## Root Cause

The module author has retracted a version, marking it as deprecated or insecure, but go.mod still references it.

## Version Compatibility

| Version | Status | Introduced | Deprecated |
|---------|--------|------------|------------|
| 1.16 | active | — | — |
| 1.17 | active | — | — |
| 1.18 | active | — | — |
| 1.19 | active | — | — |
| 1.20 | active | — | — |
| 1.21 | active | — | — |
| 1.22 | active | — | — |
| 1.23 | active | — | — |

## Workarounds

1. **Run 'go mod tidy' to automatically upgrade to a non-retracted version** (90% success)
   ```
   go mod tidy
   ```
2. **Manually upgrade to a specific newer version** (85% success)
   ```
   go get example.com/module@v1.1.0
   ```

## Dead Ends

- **Ignoring the warning and continuing to build** — Builds may succeed, but the retracted version may have security vulnerabilities or be removed in the future. (40% fail)
- **Manually editing go.mod to re-add the retracted version** — Go will still detect it as retracted and issue the same warning. (90% fail)
