I’m re-installing my config after a logic-board failure and am having issues installing emacs.
It seems recently the elpa package spinner.el has been updated to 1.7.4.
A number of the packages I’m using in myEmacs = emacsWithPackages(epkgs: ...); here depend on spinner 1.7.3 which is available as an lz archive at https://elpa.gnu.org/packages/spinner-1.7.3.el.lzhttps://elpa.gnu.org/packages/spinner-1.7.3.el
How do I override that package in my configuration?
myEmacs = emacsWithPackages (epkgs:
(with epkgs.elpaPackages; [...]) ++
(with epkgs.melpaPackages; [...])
);
The error is as follows:

A bunch of people have the same problem (myself included) with doom-emacs. I’m new to the Emacs world, so my first idea was to report this to the nix-doom-emacs project: https://github.com/vlaci/nix-doom-emacs/issues/264 but for now, there hasn’t been any suggestions on how to workaround or fix this.
This is a known bug, caused by elpa not keeping history the way we’d like it to: ELPA packages are fetched from unstable url -> not reproducible · Issue #55 · nix-community/emacs2nix · GitHub
It needs some reviving.
The issue that sparked that one points to a workaround: Override a transitive emacs dependency - #4 by codygman
Personally I’ve been using unstable for these packages, since they’re usually not broken for long there and it’s less faff than managing overrides.

Got a workaround, at least for doom-emacs,
let
spinner-lzip = builtins.fetchurl {
url = "https://elpa.gnu.org/packages/spinner-1.7.3.el.lz";
sha256 = "188i2r7ixva78qd99ksyh3jagnijpvzzjvvx37n57x8nkp8jc4i4";
};
doom-emacs = pkgs.callPackage <doom-emacs> {
# Directory containing your config.el init.el and packages.el files
doomPrivateDir = ./doom-emacs;
emacsPackagesOverlay = self: super: {
spinner = super.spinner.override {
elpaBuild = args: super.elpaBuild (args // {
src = pkgs.runCommandLocal "spinner-1.7.3.el" {} ''
${pkgs.lzip}/bin/lzip -d -c ${spinner-lzip} > $out
'';
});
};
};
};
in {...}

Thanks @Samae that’s gotten me closer.
I’ve tried to use something similar to what @codygman posted as a workaround Overriding a transitive emacs dependency - #4 as @TLATER suggested.
But what I’ve got isn’t quite working… yet…
# ~/.config/nixpkgs/config.nix

myEmacsConfig = ./overlays/pkgs/emacs;
myBaseDir = "${toString ./..}";
emacsOverrides = self: super: rec {

elpaBuild = args: super.elpaBuild (args // {
src = (builtins.fetchurl {
url = "https://elpa.gnu.org/packages/spinner-1.7.3.el.lz";
sha256 = "188i2r7ixva78qd99ksyh3jagnijpvzzjvvx37n57x8nkp8jc4i4";
});
});
};
};
myEmacs = (((pkgs.emacsPackagesGen pkgs.emacs).overrideScope' emacsOverrides).emacsWithPackages (epkgs: with epkgs;
# CONFIG setup

'')

Thanks @Samae — I should’ve taken yours almost verbatim!
myEmacsConfig = ./overlays/pkgs/emacs;
myBaseDir = "${toString ./..}";
spinner-file = "spinner-1.7.3.el";
spinner-lzip = builtins.fetchurl {

sha256 = "188i2r7ixva78qd99ksyh3jagnijpvzzjvvx37n57x8nkp8jc4i4";
};
emacsOverrides = self: super: rec {
spinner = super.spinner.override {
elpaBuild = args: super.elpaBuild (args // {
src = pkgs.runCommandLocal spinner-file {} ''
${pkgs.lzip}/bin/lzip -d -c ${spinner-lzip} > $out
'';
});
};
};

I wonder — given that elpa has had this as an ongoing issue — if there’s a generic solution?
What if if foo.el starts producing a 404, an overlay could fall back to foo.el.lz?
Obviously need to be able to handle sha256 (either before/after unarchiving), but could that shield emacs configurations from these kinds of issues?

That was discussed in the issues
The other option is building from elpa git instead of the elpa archive, though that isn’t the most convenient thing. Or waiting for elpa to offer .lz archives of everything.
In general, transparent source mirrors seem like they’d be a good idea for a nix feature. We just need to get some people together who are willing to try and upstream that.
