+name: Cache and install APT packages
+description: >-
+  Wraps awalsh128/cache-apt-pkgs-action with the workarounds Home Assistant CI
+  needs. Removes the conflicting Microsoft apt source before any apt run, and
+  points the dynamic linker at the host's multiarch lib subdirectories so
+  shared libraries that rely on update-alternatives or postinst-managed paths
+  (eg libblas, liblapack pulled in by ffmpeg) stay reachable since the upstream
+  action does not execute postinst scripts on cache restore.
