WARNING: Upgrading to jessie using this method is not supported and could be at your own risk. Please backup your SD Card before starting!
First, open up the terminal and check you have the latest Raspbian Wheezy:
sudo apt-get update
sudo apt-get dist-upgrade
Then type:
sudo nano /etc/apt/sources.list and change wheezy to jessie so It reads:
deb http://mirrordirector.raspbian.org/raspbian/ jessie main contrib non-free rpi
# Uncomment line below then ‘apt-get update’ to enable ‘apt-get source’
#deb-src http://archive.raspbian.org/raspbian/ jessie main contrib non-free rpi
Save and then type:
sudo nano /etc/apt/sources.list.d/raspi.list
Change wheezy to jessie and add ui to the end so that it reads:
deb http://archive.raspberrypi.org/debian/ jessie main ui
# Uncomment line below then ‘apt-get update’ to enable ‘apt-get source’
#deb-src http://archive.raspberrypi.org/debian/ jessie main ui
Save and then type:
sudo apt-get update
sudo apt-get dist-upgrade
sudo rpi-update
WARNING: Depending on your internet speed and space left on your SD Card this could take a long time!
Finally, type:
sudo reboot
Once your Pi has rebooted, type into the terminal:
cat /etc/os-release
You should see the following:
PRETTY_NAME=”Raspbian GNU/Linux 8 (jessie)”
NAME=”Raspbian GNU/Linux”
VERSION_ID=”8″
VERSION=”8 (jessie)”
ID=raspbian
ID_LIKE=debian
HOME_URL=”http://www.raspbian.org/”
SUPPORT_URL=”http://www.raspbian.org/RaspbianForums”
BUG_REPORT_URL=”http://www.raspbian.org/RaspbianBugs”
If you do, then you have successfully upgraded your system to Raspbian Jessie!
If you still see wheezy instead of jessie then you may not of upgraded properly! Repeat the process.
If you are having problems, please comment on this post!
