error: attribute 'libubox20220927' missing

I put together a simple repo here:

$ nix build github:jfly/nix-openwrt-imagebuilder-bug-demo/missing-libubox20220927#my-router

There is a new OpenWRT prerelease "23.05.0-rc1" which is still incomplete. This caused trouble before!

Fix by pinning to the stable API:

--- flake.nix
+++ flake.nix
@@ -8,7 +8,7 @@
       let
         pkgs = nixpkgs.legacyPackages.x86_64-linux;

-        profiles = openwrt-imagebuilder.lib.profiles { inherit pkgs; };
+        profiles = openwrt-imagebuilder.lib.profiles { inherit pkgs; release = "22.03.5"; };

         image = profiles.identifyProfile "linksys_e8450-ubi";
       in

Should I rather filter out -rc versions?

[jfly]

Ah, thank you! What if I want to follow the latest, non-prelease version?

[astro]

Given the problems we encounter with the prelreleases, I am starting to think that nobody wants that in their unattended image building pipeline. Stable OpenWrt releases only from now on!

I just hope this won't repeat itself while the .0 release is being uploaded... :-)
