Problem

E2E has failed on main since #602, in all five shards, before any test runs:

E: Unable to locate package python3.12-venv
##[error]Process completed with exit code 100.

#602 didn't cause it: it only touched build/venv-test-ipywidgets8-requirements.txt, which nothing in the repo reads. The cause is the runner image. GitHub is moving ubuntu-latest to Ubuntu 26.04 (actions/runner-images#14748, rollout Oct 19 – Nov 19). Our last green E2E run (41797583713) ran on ubuntu-24.04; the first red one (41922220528) ran on ubuntu-26.04. Ubuntu 26.04's system Python is 3.14, so its archive has no python3.12-venv.

Fix

Stay on ubuntu-latest and drop python3.12-venv from the apt install. The job never needed it:

• Every venv in the job (test/e2e/helpers/venv.ts, the interpreter suite) is created by bare python3. That resolves to the 3.12 that actions/setup-python puts first on PATH, and that build includes ensurepip.
• On 24.04 the package came preinstalled (python3.12-venv is already the newest version in the green log), so the line never changed anything there.

The interpreter suite's prerequisites comment pointed at the package, so its CI note is removed.

Verification

• Checked in an ubuntu:26.04 container, using the runner's actions/python-versions 3.12.15 build installed the way setup-python installs it: python3 -m venv works with no *-venv package, and the new apt list installs cleanly.
• This PR's E2E run is the end-to-end check on a 26.04 runner.

Summary by CodeRabbit

• Chores
  • Adjusted automated test setup to require Python that can create virtual environments, without explicitly installing a version-specific virtual-environment package.
  • Other listed runtime components remain unchanged. This update affects test setup only and does not change application functionality or the product experience.

Walkthrough

The E2E workflow no longer installs python3.12-venv; it continues to install python3-pip. The interpreter test prerequisite still requires python3 to be available and able to create a virtual environment, but no longer states that CI installs the removed package.
