Raspberry Pi Installation¶
Download Ubuntu MATE 16.04.2 LTS for Raspberry Pi 2 and 3 systems from here
Open the downloaded file with Keka.
Ubuntu desktop requires you to initially login with a keyboard and monitor to setup the system.
Once logged in, you should use
sudo raspi-config to:
- enable SSH
- turn off GUI on init
- turn off splash screen on init
- expand the filesystem
Cleanup installed packages¶
View all the packages installed by default with:
sudo apt list --installed
Remove unnecessary packages with:
1 2 3 4 5 6
sudo apt-get remove --purge vlc* youtube-* yelp-* libreoffice* thunderbird* sudo apt-get remove --purge transmission* scratch* firefox* rhythmbox* python-minecraftpi sudo apt-get clean sudo apt-get autoremove
Add developer packages¶
Add developer packages with:
sudo apt-get install git

Disable Wifi on Ubuntu¶
To disable wifi, use this /etc/network/interfaces:
1 2 3 4 5 6 7 8 9 10
# interfaces(5) file used by ifup(8) and ifdown(8) # Include files from /etc/network/interfaces.d: source-directory /etc/network/interfaces.d # The loopback network interface auto lo iface lo inet loopback auto eth0 iface eth0 inet dhcp
In the event that wlan0 is still appearing with an ip address in
Enable Wifi on Ubuntu¶
If the wifi choices are stippled, try this:
sudo /etc/init.d/networking restart
- Edit file /etc/NetworkManager/NetworkManager.conf and change managed=false to managed=true
sudo killall NetworkManager
To manage wifi connection via a config file, add this to /etc/network/interfaces:
1 2 3 4
auto wlan0 allow-hotplug wlan0 iface wlan0 inet dhcp wpa-conf /etc/wpa_supplicant/wpa_supplicant.conf
If a device is not managed in /etc/network/interfaces, then it will be avialable via the GUI.

After installing Desktop, click on Additional Drivers in Software & Updates and add machine-specific drivers.
Under the VirtualBox Networking options, set "Attached to:" to "Bridged Adapter"
