So it appears the Debian project and Beaglebone.org have stopped making updates to the Debian 8 (Jessie) release. For the Beagle, Debian 8.11 seems to be the last release. It has been run by a number of customers for a long time and also by us. So it seems safe now for Kiwi owners generally to do an upgrade and get the benefit of whatever security patches there have been between 8.5 and 8.11.

To do this login as root using ssh/PuTTY and use the following commands. (this can not be done from the Kiwi admin console tab)
If you haven't logged in this way in a while remember that your Debian root password has likely been changed to either the Kiwi admin password or the Kiwi's serial number if no Kiwi admin password has been set. The Debian root password has not been touched if you had set it to something other than the default of having no password.
See this post for details: http://forum.kiwisdr.com/discussion/1801/v1-354-security-improvements-debian-root-password-no-longer-unset-blank

cdp
mst (stops the Kiwi server)
cd
pkup (shell alias for "apt-get -y install debian-archive-keyring; apt-get update")
pkug (shell alias for "apt-get -y dist-upgrade") (lots of output, takes roughly 10 minutes) reboot

A few minutes after the reboot the Kiwi server should be responding again. If you login to the Beagle and type the "dog" command you should see:

Debian 8.11
BeagleBoard.org Debian Image 2016-05-13
Linux kiwisdr 4.4.9-ti-r25 #1 SMP Thu May 5 23:08:13 UTC 2016 armv7l GNU/Linux

There is still the open question of how the Kiwi distribution, and thousands of Kiwi customers, will migrate to the current Debian 9 (Stretch) and/or Debian 10 (Buster) releases which are available for the Beagle. This needs time for research as there are many issues involved. (less)
