Set static IP on Ubuntu Core and install my media stream server

Now I’d like to change my machine to use a static IP to be easier to log in remotely.

Subnet: 192.168.1.0/24
Address: 192.168.1.101
Gateway: 192.168.1.1
Name servers: 8.8.8.8

The root account is disabled by default in Ubuntu, so there is no root password, that’s why su fails with an authentication error.

user@host:~$ sudo bash
root@host:~# su
root@host:/home/user#
