I'm following the Plutus Env: Setup Starter Pack guideline to run a Plutus Playground Local Instance. At step 4, when running the command nix-shell, I got the error message error: invalid character in Base64 string: ''. Does anyone know how to fix it? I'm using WSL2 with Ubuntu 20.04 distro.
All the steps I did are:
- Download the plutus-apps repository: git clone https://github.com/input-output-hk/plutus-apps
- Go to the latest commit of the repository: git checkout 7f53f18dfc788bf6aa929f47d840efa1247e11fd
- Setup IOHK binary cache (https://github.com/input-output-hk/plutus-apps#iohk-binary-cache) and then at top of this repo, nix-build -A plutus-playground.server
- Enter nix-shell => error: invalid character in Base64 string: ''
Here are the outputs of nix-build, nix-shell, nix-shell --show-trace
