Remove types.string

[Profpatsch]

types.string has been deprecated for a long while now, we should remove it.

1. Remove usage in nixpkgs

Scope:

$ git grep "types\.string;" | wc -l
205

2. Use builtins.trace to deprecate it.
3. Remove in next NixOS release

[Profpatsch]

$ git grep "types.string;" | wc -l
205

Oh, that’s interesting. My ag search turned up no usage, but maybe I did it wrong.

1. and 2. have been done in 03391cd (Properly deprecate types.string #66346)

Checking right now in master gives 0 usages. The deprecation text does not say that the type will be removed in the next NixOS release, should that be added?

Thank you for your contributions.
This has been automatically marked as stale because it has had no activity for 180 days.
If this is still important to you, we ask that you leave a comment below. Your comment can be as simple as "still important to me". This lets people see that at least one person still cares about this. Someone will have to do this at most twice a year if there is no other activity.
Here are suggestions that might help resolve this more quickly:

1. Search for maintainers and people that previously touched the
   related code and @ mention them in a comment.
2. Ask on the NixOS Discourse. 3. Ask on the #nixos channel on
   irc.freenode.net.

I’ll take a look.

Hi any updates on removing the types.string deprecation error? I am just now getting into Nix and NIxOS ecosystem and I cannot rebuild my configuration due to multiple module/nixpkg references coming from this deprecated type error. Kindly advise.

[nixos@shogun:/mnt/c/Users/$USER/WSL]$ sudo nixos-rebuild switch --flake /etc/nixos#
building the system configuration...
error: The type `types.string` is deprecated. See https://github.com/NixOS/nixpkgs/pull/66346 for better alternative types.
(use '--show-trace' to show detailed location information)

@RyzeNGrind I just ran into the same issue. In my case, I was unknowingly mixing nixos-unstable with the home-manager 23.05 release branch. Switching to home-managers master branch fixed it for me.

In any case, you can run nixos-rebuild with --show-trace (and possibly --option eval-cache false) to get an idea of what package is causing the issue.
