Hi, i have upgraded to Ubuntu 16.04 after the WATCHDOG_EXPIRED issue
, now when i try to run the script shows this error message:

/vivo.js:7
const masterNodes = [...mns.split(',')]
^^^

SyntaxError: Unexpected token ...

The only difference i saw when i used on Ubuntu 14.04 is that i didn't have the "node" program, when i run the script i got this message:

The program 'node' is currently not installed. You can install it by typing:
apt install nodejs-legacy

So i installed the package with apt-get install nodejs-legacy
