picast on Ubuntu MATE 16.04 #33

I have an Ubuntu Mate 16.04 running on the Pi.
I am using the setup.sh script to get picast intalled.

The script works fine, till it states the following error:

setup.sh: 63: read: Illegal option -n

setup.sh: 65: setup.sh: [[: not found

Maybe the read tool in ubuntu is different?
"read: usage: read [-ers] [-a array] [-d delim] [-i text] [-n nchars] [-N nchars] [-p prompt] [-t timeout] [-u fd] [name ...]"

Do you have any idea? (I am not the Linux pro, so sorry if the solution is trivial)

And when I try to start picast I get the following message:

user1@pi02:~/PiCAST$ /etc/init.d/picast start
/usr/bin/env: ‘node’: No such file or director

The rights seems to be ok
user1@pi02:~/PiCAST$ ls -lah /etc/init.d/ | grep picast
-rwxr-xr-x 1 root root 360 Apr 29 15:29 pi

Do you have any idea?

In which path should this .cfg file, which is mentioned in the youtube tutorial has to be?

Cheers!
