Issue : awalsh128/cache-apt-pkgs-action#44

Without apt-get install:

https://github.com/crdoconnor/apt-cache-bug/actions/runs/2796959595

Failure is expected here

On first run with the apt package cacher:

https://github.com/crdoconnor/apt-cache-bug/actions/runs/2796966025

Should work. apt-get install is run for read.
