- **Fix Rate:** 80%

## Root Cause

pip refuses plain HTTP index hosts by default; an internal mirror over HTTP is filtered out, so its packages appear unavailable.

## Version Compatibility

| Version | Status | Introduced | Deprecated |
|---------|--------|------------|------------|
| 3.8 | active | — | — |
| 3.9 | active | — | — |
| 3.10 | active | — | — |
| 3.11 | active | — | — |
| 3.12 | active | — | — |

## Workarounds

1. **** (95% success)
   ```
   pip config set global.index-url https://my.internal.pypi/simple
pip install internal-pkg
   ```
2. **** (90% success)
   ```
   pip config set global.trusted-host my.internal.pypi
pip config set global.extra-index-url http://my.internal.pypi/simple
pip install internal-pkg
   ```

## Dead Ends

- **** — The internal package does not exist on public PyPI; the index-url override hides the internal mirror entirely. (90% fail)
- **** — DNS resolution is not the issue; pip's HTTP trust policy is. (90% fail)
