few minutes investigation:
Sorry for screens, but server is inside virtualbox and copy/paste do not works
The following applets are currently defined:
• dnsmasq: configure dnsmasq for LTSP
• image: generate a squashfs image from an image source
• info: gather support information about the LTSP installation
• initrd: create the ltsp.img initrd add-on
• ipxe: install iPXE binaries and configuration in TFTP
• kernel: copy the kernel and initrd from an image to TFTP
copy/paste on 😉
sudo apt install ltsp-binaries; sudo ltsp ipxe
Then boot a client; if it doesn't boot then paste a CLIENT screen, not the server output

That is so strange...
root@adasiek-VirtualBox:/srv/tftp# apt install ltsp-binaries
Czytanie list pakietów... Gotowe
Budowanie drzewa zależności... Gotowe
Odczyt informacji o stanie... Gotowe
Works like a charm now 😉

i'm setting up a new ltsp with ubuntu 22.4 and default gnome. I am trying to connect to the gnome remote desktop (rdp) but its throwing an error "internal error". I can connect rdp to the ltsp server as well as a desktop in the network running the same software from a hard disk instead of network boot.
anyone seen this issue before? I'm banging my head against the wall

You can connect via rdp to the server but not to the clients?
yes, the socket is available when I use netstat -taop
tcp6 0 0 :::3389 :::* LISTEN 3010/gnome-remote-d
|09:07||XYZ has joined IRC (XYZ!~XYZ@37-48-48-139.nat.epc.tmcz.cz)|
it's very neat if it works but I found few means of troubleshooting it
One reason I can think of, is if you're using SSHFS, then gnome-keyring won't work there; and rdp may depend on that
Try with NFS home to check if that's indeed the issue
I reported that issue to gnome-keyring like 10 years ago; it should be just 5-10 lines to fix it; and yet noone bothers :D

replacing sshfs with nfs does solve the issue
since there isn't any interest in keeping the home directory private that should be ok

I want to add a ramdisk and load java, javacache and the main application for the users onto the ramdisk for performance reasons. what is the recommended way to add a ramdisk to the clients?
maybe better put them to main image.... it will be uncomress to RAM on client...
so just put the outside the home and it will be included in the "main image"
or /tmp in memory defined in fstab
ok, I didn't find a /tmp in fstab but I found /run/user/1000/ being tmpfs. I suppose this is indeed in ram.
I'll try to put everything onto that location
trendzetter, I actually spent a few hours last night debugging all kinds of applications not working with the strangest errors on Ubuntu 22.04
Turned out my NFS exports file was wrong, so the clients did a fallback to sshfs. That breaks literally everything.
Or more specifically - it breaks systemd, which breaks dbus, which breaks pulseaudio, which breaks everything.
Strange... I have SSHFS and dbus etc... works fine -> latest Mint Mate Edition
Ubuntu Mate 22.04, upgraded from 20.04, 18.04 and 16.04
SSHFS works fine for all apps except gnome-keyring, AFAIK
Hyperbyte: try to check, if there will be the same problem, when you install Ubuntu from scratch. I know, teoretycly there should be no difference.. but who knows?
know - new machine for this (or at least one hard drive).. but can be worth to check
