How to specify `programs.sqlite` for `command-not-found` from flakes?

You can either replace the current command-not-found module with the one provided by nix-index (it provides both a module for nixos and home manager, thanks K900).

The second approach I can imagine is to manually download the database from https://channels.nixos.org (code not tested)

{ pgks, ... }:
let
  # To find the channel url I went in:
  # https://channels.nixos.org/ > nixos-22.05 > nixexprs.tar.gz
  # All the available channels you can browse https://releases.nixos.org
  nixos_tarball = pkgs.fetchzip {
    url = "https://releases.nixos.org/nixos/22.05/nixos-22.05.3737.3933d8bb912/nixexprs.tar.xz";
    sha256 = "sha256-+xhJb0vxEAnF3hJ6BZ1cbndYKZwlqYJR/PWeJ3aVU8k=";}
  ;
  # extract only the sqlite file
  programs-sqlite = pkgs.runCommand "program.sqlite" {} ''
    cp ${nixos_tarball}/programs.sqlite $out
  '';
in
{
  programs.command-not-found.dbPath = programs-sqlite;
}
