The rasbberry pie 3 sports a :

  • 1.2GHz 64-bit quad-core ARMv8 CPU
  • 1GB RAM
  • 802.11n Wireless LAN
  • Bluetooth 4.1
  • 4 USB ports
  • Ethernet port
  • VideoCore IV 3D graphics core

In this post we'll look at how to setup the raspberry with Ubuntu 16 server.

When you buy a new raspberry, only the board is included, so to get started you will need (at minimum): an Ethernet cable, a power adapter (microUSB),

rasberry pi images

Extract the file (you can use 7-zip for this) and you'll end up with an .img file that can be placed on an empty SD card - 

ubuntu image

 To burn the image to the sd-card get the Win32DiskImager program, run it as administrator and select the image extracted earlier:

win32disk imager a

 

 

win32disk imager b

 

 

 

 

 

 

 

Now select the drive to write the image to: 

 

win32 disk imager select device

Make sure you don't accidentally choose your harddrive as this will wipe the drive completely.

Click on 'write' and wait for the process to finish - this might take a while aprox. 10 minutes on usb-2

Once the write is finished exit the disk imaging program and eject the device.

Next up is inserting the SD-card, attaching the network interface to a port on your router, and connecting power.

When the unit has successfully booted up, you can connnect to it using putty, - add the pi's ipadress in the adress field, and connect, accept the unknown hostwarning - and login using 'ubuntu' as username and 'ubuntu' as password, - once you get logged in - you are prompted to change your password, choose something complex (we'll set up public-private key based auth later on).

Once you've changed your password you will be logged out - log in again, and you are ready for setting up your raspberry pie.

Initial setup

We'll start by adding a costum PPA and update and upgrade the system

 [email protected]:~$ sudo add-apt-repository ppa:ubuntu-raspi2/ppa-rpi3
[email protected]:~$ sudo apt-get update
[email protected]:~$ sudo apt-get dist-upgrade

This process might take a while to complete,

Now we have a base system.
