Hello. I'm finally replacing my single nic 10.04 Ubontu LTSP classroom server with a new box. I have found Alkis' writeup on how to do a single nic install. My new system is a 64 bit box and I wonder how I should generate an i386 image for my classroom clients?

Here's the page that I've been following:

https://help.ubuntu.com/community/UbuntuLTSP/ltsp-pnp

The instruction:

ltsp-config lts.conf

generates /var/lib/tftpboot/ltsp/amd64/lts.conf ...  a 64 bit labeled file

ltsp-update-image --arch i386 doesn't work as the --arch isn't recognized...
/usr/sbin/ltsp-update-image: unrecognized option '--arch'

Also, I suppose the procedure only works with a 32 bit system as the ltsp.conf file listed refers to-

gedit /var/lib/tftpboot/ltsp/i386/lts.conf

I sure could use some suggestions. I had already ordered the parts for a new server and they arrived last Friday. I rebuilt an image on my old Ubuntu server on Monday that includes the mit app inventor. I powered the machine off after the image was created to blow it out only to discover that the power supply was bad and already fried part of the motherboard. I had been running it headless and hadn't noticed the video was gone. I did notice a smell last week though... $@#@%@

At least I have the new parts and I'm close to being back up.

Thank everyone


If you use the LTSP-PNP setup, your client and server installation architectures have to match. So if your clients need i386, then you have to install Ubuntu i386 on the server as well.

If you really want x64 on the server, then you have to use the classic LTSP setup with a chroot environment and i386 installed there in order to generate an i386 client image.
