Again this has been fixed upstream in LTSP for a long time.

The problem is that Ubuntu, from 12.10 to 15.10, has a broken LTSP, and needs someone to do the steps for an SRU in order to get a newer LTSP backported:

Using this PPA "sudo add-apt-repository ppa:ts.sch.gr" which gives LTSP version 5.5.5~r2703+p1238+201512091628~ubuntu15.10.1 I get the error mentioned above.

What version of LTSP is needed to resolve this error?

[Alkis Georgopoulos (alkisg)]

You need to add that repository in the chroot as well.

Added that repo to the chroot.

Then exited back to the regular server and rebuilt the image (ltsp-update-image). Now ubuntu client boots.

Thanks

Same problem on 14.04: worked with kernel 4.2 on the host and 3.13 in the chroot but not with 4.4 on both. Workaround helped, thanks a lot, Alkis, but I really hope this gets more attention and gets fixed very soon.

> I really hope this gets more attention and gets fixed very soon.

It is already fixed. We (LTSP developers) fixed it years ago.

Now it's a matter of Ubuntu 14.04 users like you to follow the steps for an SRU and get the fix to Ubuntu 14.04:
https://wiki.ubuntu.com/StableReleaseUpdates

If no Ubuntu 14.04 user does those steps, the fix will *never* go to the Ubuntu 14.04 repositories.

But OK no big deal our PPA works fine.
