Wheezy and Jessie are words thrown around the Raspberry Pi community frequently. What do they mean and why should you care?
Wheezy and Jessie are both codenames for the Debian operating system releases. As Raspbian is based off Debian, it too uses these same codenames to describe the releases. Think of them kind of like Windows release (XP, Vista, 7, 8 10 etc).
PiNet has until December 2016, only supported Raspbian Wheezy. There were a number of reasons for this, primarily around stability for educators. This primary issue has been resoled with a PiNet package repository of its own allowing the upgrade process to PiNet Jessie progress.
As of right now (26th Dec 2016), PiNet Jessie is available in Alpha only and is not recommended for production use (in a school for example). Over time, the release will make its way to the Beta channel and eventually Stable.
The short answer, a lot! The slightly longer answer can be found in the initial release changelog.
Great, there are 2 separate processes depending on if you already have a PiNet server setup.
Open a terminal on your PiNet server and type the following commands.
sudo mv pinet-functions-python.py /usr/local/bin
sudo bash pinet
Follow onscreen instructions to upgrade. Make sure to select Alpha as your release channel.
Follow the normal installation instructions for Ubuntu, then open a terminal and run the following commands.
wget --content-disposition http://links.pinet.org.uk/jessie-alpha-pinet
sudo bash pinet
Follow onscreen instructions for the installation. Make sure to select Alpha as your release channel.
