I did a normal install of Ubuntu 12.04 using the Alt ISO. When I try to install ltsp-server-standalone I get:
ltsp@ubuntu32:~$ sudo apt-get install ltsp-server-standalone

Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:
The following packages have unmet dependencies:
ltsp-server-standalone :
Depends: ldm-server but it is not going to be installed
Depends: ltsp-server but it is not going to be installed
Depends: ltspfs but it is not installable
Depends: nbd-server (>= 1:2.9.25-2) but it is not installable
Recommends: isc-dhcp-server but it is not going to be installed
Recommends: pulseaudio-esound-compat but it is not going to be installed
E: Unable to correct problems, you have held broken packages.
I would like to use 12.04 because alot of the ltsp guides are based on it.
