How to update the Go version

System: Debian/Ubuntu/Fedora. Might work for others as well.

1. Uninstall the exisiting version

As mentioned here, to update a go version you will first need to uninstall the original version.

To uninstall, delete the /usr/local/go directory by:

ryder247

version: '3.8'
services:
  mongo: 
    image: mongo:7.0
    environment:
      MONGO_INITDB_ROOT_USERNAME: mongadmin
      MONGO_INITDB_ROOT_PASSWORD: LikeAndSubscribe
    ports:
      - 27017:27017
    volumes:

#!/bin/bash

if [ "$1" = "start" ]; then
  echo "Starting Lightning Network"
  echo "====================="

  sudo service lnd start &
  lncli unlock
elif [ "$1" = "stop" ]; then
  echo "Stopping Lightning Network"
