Problem

The python3 -m venv command used to install bloc was failing because the python3-venv package was not installed.

Root Cause

Previous attempts missed the fundamental issue: On Debian/Ubuntu systems, the venv module is not included in the base python3 package — it requires a separate python3-venv package.

The three previous approaches failed because:

  1. PR #26: Used uv tool install but didn't address venv
  2. PR #28: Attempted system-wide install with different flags
  3. PR #29: Switched to venv approach but didn't install python3-venv

Solution

Added python3-venv to the initial apt-get install alongside python3 and python3-pip.

This is the correct fix because:

  • ✅ Addresses the actual error message: "you need to install the python3-venv package"
  • ✅ Installs the package BEFORE attempting to create the venv
  • ✅ Follows Debian best practices (separate -venv package)
  • ✅ Minimal change with no side effects

Testing

The error message was explicit: ensurepip is not available. On Debian/Ubuntu systems, you need to install the python3-venv package.

This directly resolves that requirement.

Fixes #30

The bloc installation uses python3 -m venv to create a virtual environment,
but python3-venv was not installed. This is required on Debian/Ubuntu systems.
