The second waffle
Unfortunately, the attempt to set up the Pi’s last week didn’t work very well. Most of them had problems with names, accounts, etc. But, as Al Davis says, you always throw away the first waffle.
The Pi cards have been rewritten with the latest distribution and the magic ssh file has been added so to the boot partition that they can be connected to externally.
So we are starting again. At the point, you must know the letter on your Pi.
For this document, I’ll use α. If you
see α type in the letter on your Pi. Do not be creative.
If you don’t have an https://help.ubuntu.com/community/SSH/OpenSSH/Keys, get one before starting.

Starting it up
Do not be afraid to ask advice from the people around you or the instructor. Do the following.
- plug in your Pi
- Use ssh to connect to your Pi.
- Start raspi-config.
- Change the password. Use your UNC Asheville so you won’t forget.
- Change your computer’s hostname to uncacsci-pi-α.cs.unca.edu Do not be creative!
- Change boot mode to console with login.
- Change locale to use en_US.UTF-8 .
- Change timezone.
- Under interfacing options, enable ssh&bsp;. This is probably the most important step!
- Enable I2C
- Exit raspi-config an reboot.
Second connection
See if it starts up. Login with your pi account.
Type id to make sure you are in the right groups.
Use the adduser to create a uncacsci
account with the password AhoyMates.
Add the account to the sudo group.
Get the instructor to check out the account and your setup.
Third connection
If there are 45 minutes of so left in the class, you can use apt-get to start update the Raspberry Pi operating system. If not, we can move your Pi to another room. Or, we can just leave your Pi in RRO 223 until CSCI 235 meets that everning.
sudo apt-get update sudo apt-get dist-update sudo shutdown -r now
In case you finish really early
Go help someone else until they are done.
