[Ltsp-discuss] Newer thin clients not booting?

[Joseph Bishay]

Good afternoon,

I hope everyone is doing well.

We've been running Edubuntu 14.04.05 LTS for a while and it has been
amazing. Both thick and thin client setups are working fine.

We tried to add some new hardware as thin clients, but they will not
boot up. They seem to PXE boot correctly, then drop into busybox.

All the working thin clients are old Core 2 Duo machines or older.
All the new thin clients that will not work are newer i3, i5, or i7
machines.

Has anyone come across this? How can I fix this please?

Hello,

Thank you very much for your reply and that link. I had thought that
using apt-get dist-upgrade would be sufficient.

I am running LTS 14.04.5. The link has a section for 14.04, and under
it there are three different commands to run. I think it should be
multiarch but perhaps it should be server?:

+++++
Desktop
sudo apt-get install --install-recommends linux-generic-lts-xenial
xserver-xorg-core-lts-xenial xserver-xorg-lts-xenial
xserver-xorg-video-all-lts-xenial xserver-xorg-input-all-lts-xenial
libwayland-egl1-mesa-lts-xenial

Multiarch Desktop
If you run a multiarch desktop (for example, i386 and amd64 on amd64,
for gaming or Wine), you may find you need a slightly more involved
command, like this:
sudo apt-get install --install-recommends linux-generic-lts-xenial
xserver-xorg-core-lts-xenial xserver-xorg-lts-xenial
xserver-xorg-video-all-lts-xenial xserver-xorg-input-all-lts-xenial
libwayland-egl1-mesa-lts-xenial libgl1-mesa-glx-lts-xenial
libgl1-mesa-glx-lts-xenial:i386 libglapi-mesa-lts-xenial:i386

Server
Install the HWE kernel derived from 16.04 (xenial):
sudo apt-get install --install-recommends linux-generic-lts-xenial

+++++

Thank you!
Joseph
