Using LXD
If you're having issues getting ganache-cli working on my localhost environment on Ubuntu, use a LXD container.
Installing LXD
Answer default to all questions.
sudo apt install lxd zfsutils-linux && lxd init
Open two terminals on your pc to interact with container and api
Change to ganache-test-container to whatever name you want.
Terminal 1
lxc launch ubuntu:bionic ganache-test-container lxc exec ganache-test-container /bin/bash apt update && apt install nodejs npm git npm install -g ganache-cli ganache-cli
Terminal 2
PORT=8545 PUBLIC_IP=localhost CONTAINER_IP=$(lxc list | grep ganache-test-container | awk -F\| '{print $4}'| awk '{print $1}'); sudo iptables -t nat -I PREROUTING -i lo -p TCP -d $PUBLIC_IP --dport $PORT -j DNAT --to-destination $CONTAINER_IP:$PORT -m comment --comment "ganache-cli"
You should now be able to connect on you localhost via localhost:8545
