[Bug 1048699] [NEW] ltsp-build-client fails when specifying old distros

[Colin Scott]

Public bug reported:

This bug report comes after a lot of frustration with trying to create
an LTSP “hardy” chroot for some old systems with now unsupported
Graphics chipsets and researching this issue. I’m using Edubuntu 12.04.
The command I’m using is “ltsp-build-client --arch i386 --dist hardy
--chroot 8.04-i386 --copy-package-lists --keep-packages --purge-chroot”
which I understand will never succeed unless the package ltsp-client-
core_5.0.40~bzr20080212-0ubuntu7_i386.deb is made installable.

Until recently any version of client package ltsp-client-core was not
installable on “regular machines”, it could only be installed chrooted
“because it required special changes to the operating system done by
ltsp-build-client”. From Edubuntu 12.04 / LTSP 5.3 the situation has
been reversed i.e. the newer versions are installable on “regular
machines” and the older ones can’t be installed chrooted.

Bug #936810 gives some background to this problem:

“In LTSP 5.3, most of those changes were moved from the chroot build
phase to the client boot phase (/sbin/init-ltsp).”

ltsp-build-client failure text:

"Unpacking ltsp-client (from .../ltsp-client_5.0.40~bzr20080212-0ubuntu7_all.deb) ...

Prompt appears as follows:

"Installation aborted

ltsp-client cannot be installed in a regular machine. This package
provides the basic structure for a LTSP terminal. . Please read the
package description to understand what it means"

Please understand that my primary goal is to save others a lot of
frustration as I have now actually given up on the ltsp-client-
core_5.0.40~bzr20080212-0ubuntu7_i386.deb not installable issue. I guess
I will have to download and install Edubuntu 11.04, which I hope is the
version before these changes were made, in order to just create an 8.04
chroot environment and then I guess I can transfer the chroot to 12.04
and destroy the temporary Edubuntu 11.04 installation?

What we absolutely need at a minimum is for ltsp-build-client to
generate an error that older distros are no longer supported in order to
save folks hours of research on this problem and maybe stop some more
duplicates of Bug 936810 being reported! I guess all the old distro
links / scripts in “/usr/share/debootstrap/scripts” can be removed from
the relevant packages as well in order to clean things up?

If there is a workaround for the ltsp-client-
core_5.0.40~bzr20080212-0ubuntu7_i386.deb not being installable using
the latest ltsp-build-client then I would be interested in knowing what
that is.
