I'm attempting to finish the setup for plutus pioneers cohort3 on wsl2 (Windows 10) with Ubunutu 20.04
Nix version: 2.5.1
I cloned the plutus-apps repo (and previously tried the plutus repo before instructions to change to plutus-apps)
I have followed several different sets of instructions, reinstalled nix, tried removing and recloning the repo, and various other potential fixes, but always get to the same error:
/plutus-apps$ nix-build -A plutus-playground.server --show-trace
error: reading from file: Is a directory
