| docker_debian-unstable-packages.md | docker | Installing packages from Debian unstable in a Docker image based on stable | https://github.com/simonw/til/blob/main/docker/debian-unstable-packages.md | For [Datasette #1249](https://github.com/simonw/datasette/issues/1249) I wanted to build a Docker image from the `python:3.9.2-slim-buster` base image ("buster" is the current stable release of Debian) but include a single package from "sid", the unstable Debian distribution. I needed to do this because the latest version of SpatiaLite, version 5, was available in `sid` but not in `buster` (which only has 4.3.0a): https://packages.debian.org/search?keywords=spatialite <img width="923" alt="Package libsqlite3-mod-spatialite stretch (oldstable) (libs): Geospatial extension for SQLite -
