Package libvirt-daemon-system is not configured yet.

I meant the whole update process from the previous version
(downgrading to the old version, then updating again).

I suspect dpkg-maintscript-helper to not identify
/etc/init.d/libvirt-bin to be related part of libvirt-bin:amd64 and
therefore not being moved out of the way. I saw a similar error when
changing the libvirt-bin transitional package to arch all.

Yes, I did. I added “linux64” before “start-stop-daemon --start […]”
#!/bin/mksh-static

So this is multiarch using mostly i386 but some x86_64? Could you
attach "dpkg -l" as well?

:i386

Yes, probably.

No, this is i386 single-arch. There is an amd64 kernel package
for this. I’ve got an amd64 schroot, which I use to run qemu
when VMs need more than 2047 MiB RAM.

***@tglase:~ $ cat /usr/local/bin/qemu-in-chroot
#!/bin/sh
exec schroot -c sid-amd64 -u root -- qemu-system-x86_64 "$@"

Then, <emulator>/usr/local/bin/qemu-in-chroot</emulator>
in the domain XML, and it works.

Thanks
 downgrading killed the VMs I had running, errored
out, and did all other sorts of trouble. Don’t suggest that
to “newbie” users ;-)

Anyway, did it. typescript attached.

Hi,
Thanks for reporting back.

DEBUG: dpkg-maintscript-helper: Executing /usr/bin/dpkg-maintscript-helper mv_conffile in preinst of libvirt-bin
DEBUG: dpkg-maintscript-helper: CONFFILE=/etc/default/libvirt-bin -> /etc/default/libvirtd PACKAGE=libvirt-bin:i386 LASTVERSION=1.2.6-1~ ACTION=upgrade PARAM=1.2.4-3.2
DEBUG: dpkg-maintscript-helper: Executing /usr/bin/dpkg-maintscript-helper mv_conffile in preinst of libvirt-bin
DEBUG: dpkg-maintscript-helper: CONFFILE=/etc/init.d/libvirt-bin -> /etc/init.d/libvirtd PACKAGE=libvirt-bin:i386 LASTVERSION=1.2.6-1~ ACTION=upgrade PARAM=1.2.4-3.2

Renaming a conffile
[..snip..]
Current implementation: the preinst checks if the conffile has been modified, if yes it's left on place otherwise it's renamed to old-
conffile.dpkg-remove. On configuration, the postinst removes old-conffile.dpkg-remove and renames old-conffile to new-conffile if old-
conffile is still available. On abort-upgrade/abort-install, the postrm renames old-conffile.dpkg-remove back to old-conffile if
required.

So since you modified /etc/init.d/libvirt-bin it's left in place and
when insserv runs in the postinst there is /etc/init.d/libvirt-bin and
/etc/init.d/libvirtd both providing libvirt-bin which breaks insserv.

The situation would be improved if we'd moved the conf file rename
_prior_ to the insserv (added by dh_installinit). Is this possible
with debhelper without open coding it?

But this still isn't enough. If you didn't modify
/etc/default/libvirt-bin then this file would be renamed to
/etc/default/libvirtd and the nonexistent /e/d/libvirt-bin would
result in start_libvirtd != yes and the daemon wouldn't be started
again.

So we additinally need to add a symlink from /etc/default/libvirt-bin
to /etc/default/libvirtd (since this is what your then renamed script
would source).

The simplest solution would be to just remove libvirt-bin from the
Provides in the init script headers. Nothing else in Debian seems to
require it. Only nova-compute has it in the Should-Start and that
could easily be fixed (and a Breaks: added to libvirt-daemon-system).

I'm cc'eing Raphael since he might have encountered this before.
Cheers

Sounds like fun=E2=80=A6

What do I do now, manually remove the old initscript then retry?

Yes, just remove /etc/init.d/libvirt-bin as a work around.
