Installing Debian 8.11

To install Debian 8.11 (jessie), download any of the following images (all i386 and amd64 CD/DVD images can be used on USB sticks too):

netinst CD image (generally 150-280 MB)

Blu-ray (via jigdo)

other images (netboot, flexible usb stick, etc.)

If any of the hardware in your system requires non-free firmware to be loaded with the device driver, you can use one of the tarballs of common firmware packages or download an unofficial image including these non-free firmwares. Instructions how to use the tarballs and general information about loading firmware during an installation can be found in the Installation Guide (see Documentation below).

netinst (generally 240-290 MB) non-free CD images with firmware



If you read only one document before installing, read our Installation Howto, a quick walkthrough of the installation process. Other useful documentation includes:

Errata for release 8.11

pkgsel does not install updates with ABI changes (by default)
Bug #908711: during installation with network sources enabled, the installed security updates don't include updates that depend on a new binary package, due to a kernel or library ABI change.
Status: This has been fixed in the installer included for newer releases (Debian 9 stretch). For Debian 8 installations, since no new Debian installer is provided, security updates that depend on new packages should be installed manually:
- Run apt-get upgrade --with-new-pkgs
- Reboot to complete the upgrade.
APT was vulnerable to a man-in-the-middle attack
A bug in the APT HTTP transport method (CVE-2019-3462) could be exploited by an attacker located as a man-in-the-middle between APT and a mirror to cause the installation of additional, malicious, packages.
This can be mitigated by disabling use of the network during initial installation and then upgrading following the instructions in DLA-1637.
Status: This has been fixed in 8.11.1

Errata for release 8.0

Desktop installations may not work using CD#1 alone
Due to space constraints on the first CD, not all of the expected GNOME desktop packages fit on CD#1. For a successful installation, use extra package sources (e.g. a second CD or a network mirror) or use a DVD instead.
Status: It is unlikely more efforts can be made to fit more packages on CD#1.
Powerpc boot messages are out of date
Bug #783569: powerpc CDs still talk about using the kernel command line to select a desktop, which is now obsolete - use the tasksel menu instead.
Status: This has been fixed in 8.1
Problems installing more than one desktop task at once
Bug #783571: It's not possible to install both GNOME and Xfce at the same time. There is a conflict in dependencies that causes package installations to fail.
Status: This has been fixed in 8.1
