The "Refresh APT repositories" step ran `apt-get update` only on an APT cache miss. On a cache hit the index was left stale, so `apt-get install` failed with 404 Not Found when a pinned package version had been rotated out of the mirror (e.g. libcurl4-openssl-dev). Run `apt-get update` unconditionally: it is cheap and the APT cache still serves the .deb downloads. Applied to workflows/_python.yml and its hard-linked .github/ self-test copy.
