It doesn't work out of the box.

But you could try to install a combi server offline following these 

Unplug all (real, virtual) network cables. 

Add 'edu-skip-ltsp-make-client' as kernel param (see manual) to build 
the chroot for Thin Clients as a first step. See the manual for details.

Continue the installation as usual. DHCP will fail, choose 'Don't 
configure the network at this time' or some such.

If 'Select and install software' is at 10%' wait a minute or two, then 
hit <CTRL-ALT-F2> and activate the console to get a shell: a file inside 
the Debian Installer target has to be modified (editor 'nano' is used, 
so basic knowledge about nano is needed).

The USB ISO image Release file is rated as expired; to work around this 
issue, run

'nano target/usr/share/ltsp/plugins/ltsp-build-client/Debian-custom/015-edu-apt-source' 
(Use <TAB>; it works in the Debian Installer environment, just try until 
the file shows up).
Add an additional param to APT_GET_OPTS so that you have:

               --allow-unauthenticated -o acquire::check-valid-until=0"

Save the modified file.

Change back to the Debian Installer GUI (<CTRL-ALT-F5>), wait quite some 
time until the installation is finished (but really isn't yet).
So don't hit return!

Instead, change back to the Debian Installer console.
run 'chroot target bash'
run 'nano /opt/ltsp/i386/etc/apt/sources.list'
uncomment the 'file:///' entry
comment both 'http://' ones

Mount cdrom:
run 'mount /dev/sXX /opt/ltsp/i386/media/cdrom'
(replace sXX with your actual USB stick device)
run 'ltsp-chroot -m apt-get --allow-unauthenticated -o acquire::check-valid-until=0  update'

Install the desktop of your choice, e.g. Xfce; several are ok as well:
run 'ltsp-chroot -m apt install education-desktop-other education-desktop-xfce'
(Choose <No> if prompted by jackd)

run 'ltsp-update-sshkeys'
run 'ltsp-update-kernels'
run 'ltsp-update-image -n'

run 'nano /opt/ltsp/i386/etc/apt/sources.list'
and undo the previous changes.

Change back to the GUI and hit <Return>.

The combi server should now be usable with both Thin Clients and 
Diskless Workstations.

Don't forget to update system and LTSP chroot once connected to the 

Good luck,
