-# Add Debian's oldstable repository to ensure access to llvm-9-dev if it's considered "older"
-# for the default slim image's sources.
-# This ensures we can find packages that might not be in the primary/current stable sources.
-# It's important to use the correct release name for oldstable (e.g., bullseye, buster).
-# For Python 3.9-slim (Debian 11 Bullseye), bullseye is the current stable, so llvm-9-dev should be there.
-# Let's ensure the regular apt sources are exhaustive.
