Ubuntu Server 14.10: Missing pxelinux.0 on tftpboot/ltsp/chroot

[Fabio Henrique de Souza]

I've got a fresh install of Ubuntu Server 14.010 64bit.

After installing ltsp-server and run ltsp-build-client to build a kubuntu-desktop (fatclient) , I noticed that the file pxelinux.0 is missing in tftpboot/ltsp/$CHROOT folder and $CHROOT /boot

Searching for a solution I saw that pxelinux.0 no longer comes with the syslinux package in Ubuntu 14:10 but in a new package pxelinux.

pxelinux.0 -> /usr/lib/PXELINUX no more in /usr/lib/syslinux

This is the cause of the error ?

I installed pxelinux and syslinux -common packages on server and even I rerun ltsp - build-client the problem persists .

This was fixed upstream in 5.5.2:

https://bazaar.launchpad.net/~ltsp-upstream/ltsp/ltsp-trunk/revision/2569
https://bazaar.launchpad.net/~ltsp-upstream/ltsp/ltsp-trunk/revision/2570

Ubuntu needs to both add those patches (or import a newer upstream) and update the packaging to pull in the appropriate packages.

Hi,

I installed LTSP 5.5.2 from ppa: bennabiy/testing (5.5.2-r2585+P1210+201408 290311~ubuntu14.10.1), and I get the same result running ltsp-build-client. pxelinux.0 is missing.

A couple things to check:

* The version of ltsp in the chroot is the correct version (you need to
  have the ppa packages there as well). The command "ltsp-info" should
  tell you.

* The appropriate packages are in the chroot (presuming the names are
  the same as on Debian):
  ltsp-chroot apt-get install pxelinux syslinux-common

Humm.. OK the fixes is in the client..
Ltsp 5.5.2 package from ppa no resolve the problem. Correct?

The fixes would have to be in the upstream ltsp-client code, as well as
in the ltsp-client packaging (to pull in the correct dependencies).

I neither use that PPA or Ubuntu, so can't say weather they work or not.

I tested the fixes on Debian Jessie.

Hi Vagrant,

I ran the ltsp-build-client command with these options :

ltsp-build-client --chroot kubuntu1410 --accept-unsigned-packages --early-mirror "http://ppa.launchpad.net/bennabiy/testing/ubuntu utopic main" --early-packages "pxelinux syslinux-common ltsp-client"

Obs .: PPA as a mirror

With this the ltsp-client 5.5.2 was installed on CHROOT and solved the problem of missing pxelinux.0
This does not solve the bug in Ubuntu but allows me to continue my work.

Thanks for your help,
Fabio

Status changed to 'Confirmed' because the bug affects multiple users.

This problem is also in Ubuntu 15.04 with ltsp 5.5.1-1ubuntu3 .

Hi, to get this fix backported to previous Ubuntu versions one would need to follow the SRU process:
https://wiki.ubuntu.com/StableReleaseUpdates

[Alkis Georgopoulos (alkisg)]

Since noone filed an SRU and releases <= 15.04 are EOL and it's fixed in 16.04, I'm marking this as Won't Fix in Ubuntu.
