shasum error during rebuild

[tebowy]

I've added this repo as a let…in in configuration.nix, addedd the package to the system list, and am getting this error on system rebuild.

How to fix the configuration?

Running once-off works with the enable-experimenal flakes command.

[vlinkz]

In the configuration file, try changing

    sha256 = "0000000000000000000000000000000000000000000000000000";

to

    sha256 = "sha256-Wst1UmVuE5L+1y6c96I62bXSBAcGYus3i7PFEPd4Jv0=";

I don't have the actual sha hash in the readme since it changes every update (although I probably could do it for tag releases, I'll look into it), but in your error output it shows

         specified: sha256-AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA=
            got:    sha256-Wst1UmVuE5L+1y6c96I62bXSBAcGYus3i7PFEPd4Jv0=

so replacing the zeros with the got value should fix this in the future as well

Thanks, that did help (I've got the v3 tag anyway from readme)
