The OpenRA nixpkgs package was a package I helped to maintain for a little while, but I stopped using NixOS for a few years and now I’m trying to update it. I have a more up-to-date version in my overlay. Specifically, I’d like to build the git commit version of the OpenRA engine. I know from packaging OpenRA’s git commits for the Arch User Repository that OpenRA now uses .NET SDK version 8.0 (compared to 6.0 when I last updated my overlay). So I updated the .NET package used to version 8.0. I also updated the commit to 2cb1e5f8c546196e911827e5d33f3b686c3bf452, along with its sha256 hash. I also managed to update its deps.json by running dotnet restore --packages out and nuget-to-json out > deps.json per this guide. Despite this, whenever I try to build the package, however, by adding it to my environment.systemPackages I get the error:

And I am stumped as to how to fix this error. I have tried getting GitHub’s Copilot to help me with this, but that failed (didn’t even change the error I received). If the problem path was hard-coded, I’d just add a line to remove it if I knew where to add such a line, but the nuget.[0-9a-z]* part of the path varies each time I rebuild. Also, I don’t know where I’d add such a line as I cannot see a field in the .NET packaging docs for modifying the commands run as part of the configureNuget packaging phase.
I did ask Copilot for how to do this, and it helped me get past this particular error, but it just gave me a heap of errors that seem to be due to nuget attempting to download packages in a sandboxed environment. If you want the details, I committed the changes Copilot suggested to a separate branch.
