sudo run build fails

[jocon-grmtx]

I am trying to follow the instructions to deploy neoConverse locally on my wsl2 ubuntu, but get the issue below after multiple tries. I've tried many things - updated wsl, ubuntu, tried the dev branch, upgraded node.js. No matter what, always this issue. Can anyone please assist - give me some hints? I've even tried deploying on a separate wsl 2 machine. Same. Thanks, John
