Install IPFS on Ubuntu 16.04 64bit and set up as systemd service

ipfs_install.sh

#!/bin/bash

#pick your IPFS version
VERS=0.4.13
DIST="go-ipfs_v${VERS}_linux-amd64.tar.gz"

sudo apt-get update
sudo apt-get install golang-go -y
wget https://dist.ipfs.io/go-ipfs/v0.4.13/$DIST
tar xvfz $DIST
rm *.gz
sudo mv go-ipfs/ipfs /usr/local/bin/ipfs
#initialized IPFS as 'ubuntu' user
#the systemd config also runs it as 'ubuntu'
ipfs init

#need to be root to write service file
sudo su
cat <<EOT >> /lib/systemd/system/ipfs.service

sudo systemctl start ipfs

Thanks

The script fail in reboot!!
To fix it change the 29 (WantedBy=multiuser.target) by the next:
WantedBy=default.target

And then all will be fine!
