By way of example, installing the ghc compiler: sudo apt install ghc|tee ghc.sug answer no to install packages. You get ghc.sug on your drive and can then look over the suggested packages to install. If a problem happens later since you declined to install one of the suggested packages when you actually do install ghc, you at least have a list you can use to get the necessary packages to install on your drive.
