I recently became unable to build a configuration that used to work.
It began giving me this error:
[jeff@jbb-dell:~/nix/jbb-config]$ sudo nixos-rebuild switch
unpacking 'https://github.com/nix-community/emacs-overlay/archive/master.tar.g
z'...

error: undefined variable 'intero' at /etc/nixos/emacs.nix:24:7
(use '--show-trace' to show detailed location information)
Searching NixOS Search for Intero,
I find emacs26Packages.intero, which has the name emacs-intero.
I tried replacing intero with emacs-intero,
and even with emacs26Packages.intero, but it didn’t work.
I think the problem might be that I’m using Emacs 27.1.
Here’s my Emacs configuration. Here’s the top level of my configuration, which includes the following Emacs overlay:
nixpkgs.overlays = [
(import (builtins.fetchTarball {
url = https://github.com/nix-community/emacs-overlay/archive/master.tar.gz;
}))
];
But I’ve had that since November, and had the config rebuilding nightly throughout all of January without incident. I don’t understand the overlay (or overlays generally). I think I copied it from Jethro Kuan, creator of org-roam, as a way to make sure things were sufficiently up to date that org-roam would work.
For now I’ve just deleted it from my config.
If I want it to work again, will I have to build an Intero package for Emacs 27 Or is that a red herring, and if so, how can I restore Intero?
