Symptom & Impact

Python package installs fail, blocking deployments and maintenance tasks.

Environment & Reproduction

Typical on old Python/OpenSSL stacks hitting modern package indexes.

Root Cause Analysis

Client TLS capabilities are incompatible with current PyPI requirements.

Quick Triage

Check python, pip, and openssl versions and current endpoint handshake.

Step-by-Step Diagnosis

Confirm protocol mismatch and CA store validity before remediation.

Solution – Primary Fix

Upgrade pip toolchain via supported path or controlled mirror strategy.

Solution – Alternative Approaches

Use internal package mirror with compatible TLS policies.

Verification & Acceptance Criteria

pip install succeeds for baseline package set.

Rollback Plan

Revert pip binaries and requirements lock if regressions occur.

Prevention & Hardening

Maintain pinned build images and avoid unsupported runtime drift.

Related Errors & Cross-Refs

SSL: TLSV1_ALERT_PROTOCOL_VERSION and handshake failures.
