I am linking to a similar question in which the person seemed to get it working. However, with the instructions I have followed nothing seems to work to get Haskell running.

System: Ubuntu 22.04

1) sudo apt install ghc
2) sudo apt install haskell-stack
3) sudo apt install cabal-install
4) stack new my-project
5) cd my-project
6) stack setup
7) stack build
8) stack exec my-project-exe
9) cabal init
10) cabal build
11) cabal run

I went into package.yaml and added genprog as a dependency:

dependencies:
- base >= 4.7 && < 5
- genprog

Ran

1) stack build
2) import GenProg
3) cabal init
4) cabal ucabal install --only-dependencies
pdate
5) stack build

However, I get this error:

stack build
