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 Reading package lists... Done Building dependency tree Reading state information... Done 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.
