Unfortunately, the parts that take the time are unsafe or pointless to cache. Remember that the pipeline caches may be deleted at any time, so you always need to run the commands anyway.

apt-get update doesn't use a cache, so will download the latest indexes every time.

apt-get install caches downloaded packages in /var/cache/apt so you could save that. However this probably won't actually save any time

The actual installed packages cannot be cached, because they a) are spread around multiple shared files and directories and b) may not be portable to different docker images.

At a deeper level, satisfactory interaction between caching, apt-get update, and Docker is a complex issue.
