Debian Edu 9, based on Debian Stretch, has been released
Do you have to administrate a computer lab or a whole school network? Would you like to install servers, workstations and laptops which will then work together? Do you want the stability of Debian with network services already preconfigured? Do you wish to have a web-based tool to manage systems and several hundred or even more user accounts? Have you asked yourself if and how older computers could be used?
Then Debian Edu is for you. The teachers themselves or their technical support can roll out a complete multi-user multi-machine study environment within a few days. Debian Edu comes with hundreds of applications pre-installed, but you can always add more packages from Debian.
The Debian Edu developer team is happy to announce Debian Edu 9 "Stretch", the first Debian Edu / Skolelinux release based on the Debian 9 "Stretch" release. Please consider testing it and reporting back () to help us to improve it further.
About Debian Edu and Skolelinux
-------------------------------
Debian Edu, also known as Skolelinux [1], is a Linux distribution based on Debian providing an out-of-the box environment of a completely configured school network. Immediately after installation a school server running all services needed for a school network is set up just waiting for users and machines to be added via GOsa², a comfortable web interface. A netbooting environment is prepared, so after initial installation of the main server from CD or USB stick all other machines can be installed via the network. Older computers (even up to ten or so years old) can be used as LTSP thin clients or diskless workstations, booting from the network without any installation at all. The Debian Edu school server provides an LDAP database and Kerberos authentication service, centralized home directories, a DHCP server, a web proxy and many other services. The desktop contains more than 60 educational software packages and more are available from the Debian archive. Schools can choose between the desktop environments KDE Plasma, GNOME, LXDE, MATE and Xfce.

The images can be verified using the file SHA256SUMS.asc containing signed checksums of the images; see http://ftp.skolelinux.org/skolelinux-cd/SHA256SUMS.asc Once you've downloaded an image, you can check that its checksum matches that expected from the checksum file; and that the checksum file has not been tampered with. For more information about how to do these steps, read the verification guide [4].
