# go: github.com/foo/bar@v1.2.3: reading github.com/foo/bar/go.mod at revision v1.2.3: unknown revision

- **ID:** `go/go-get-version-conflict`
- **Domain:** go
- **Category:** module_error
- **Verification:** ai_generated
- **Fix Rate:** 80%

## Root Cause

The requested module version does not exist in the remote repository, possibly because the tag was deleted or never created.

## Version Compatibility

| Version | Status | Introduced | Deprecated |
|---------|--------|------------|------------|
| 1.15 | active | — | — |

## Workarounds

1. **** (85% success)
   ```
   Check available tags with 'git ls-remote --tags https://github.com/foo/bar' and use an existing version.
   ```
2. **** (60% success)
   ```
   If the version was recently deleted, contact the maintainer or use a fork that has the version.
   ```

## Dead Ends

- **** — This does not affect version existence; the revision is genuinely absent. (90% fail)
- **** — Branches are not valid module versions unless they follow semver naming; this will cause other errors. (70% fail)
