Ubuntu setup for Plutus Playround

Steps

• [x] 1) - Clone plutus repo from here
• [x] 2) - Install NIX from here
• [x] 3) - From terminal do the following:

sudo mkdir -p /etc/nix/ mkdir -p ~/.config/nix sudo touch /etc/nix/nix.conf touch ~/.config/nix/nix.conf

• [x] 4) - Paste the following in ~/.config/nix/nix.conf and /etc/nix/nix.conf

(Note: editing /etc/nix/nix.conf required sudo)

substituters = https://hydra.iohk.io/ https://iohk.cachix.org/ https://cache.nixos.org/ trusted-public-keys = hydra.iohk.io:f/Ea+s+dFdN+3Y/G+FDgSq+a5NEWhJGzdjvKNGv0/EQ= iohk.cachix.org-1:DpRUyj7h7V830dp/i6Nti+NEO2/nhblbov/8MW7Rqoo= cache.nixos.org-1:6NCHdD59X431o0gWypbMrAURkbJ16ZPMQFGspcDShjY=

• [x] 5) - Navigate to the Plutus folder (from the Git Clone in Step 1) and paste this:

nix build -f default.nix plutus.haskell.packages.plutus-core

• [x] 6) - Open two terminal windows.
• [x] 7) - In terminal window 1 (from the root of the Plutus project):

nix-shell cd plutus-playground-server plutus-playground-server

• [ ] 8) - In terminal window 2 (from the root of the Plutus project): FAILED nix-shell cd plutus-playground-client npm run start

Setup failed at Step 8 - either nix-shell failed to complete or npm run start

Possible Reasons - WiFi connection (my connection not reliable), ThinkPad X200 ran out of memory (the machine slowed down after installation - even after a minimal image install of Ubuntu 20.04 LTS.
