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 (13th Feb 2017), PiNet Jessie is available on Alpha and Beta (previously dev) channels only and is not recommended for production use (in a school for example). Eventually, after further testing, releases will be promoted up to Stable for general use.
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.
Launch PiNet as usual and verify you are running version 1.1.10 or higher (shown at top right of PiNet control panel). If you are not running 1.1.10 or higher, you may need to change your release channel.
If you need to change your release channel, launch PiNet and select “Other”, then “Change-release-channel”. Finally, select “Development”. PiNet will restart and allow you to update to version 1.1.10 or higher.
Follow onscreen instructions to upgrade. Make sure to select Alpha (or Beta) 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 (or Beta) as your release channel.
