package libvirt-bin 1.2.8-0ubuntu6 failed to install/upgrade: subprocess installed post-installation script returned error exit status 1

[Simon THOBY]

======================================================
Impact: libvirt package upgrade can fail if user deletes /etc/libvirt/qemu.conf
Test case:
 sudo apt-get install libvirt-bin
 sudo rm /etc/libvirt/qemu.conf
 sudo apt-get install --reinstall libvirt-bin
Regresion potential: none, we only check that the file is present before trying to chown+chmod it.
======================================================

I ran sudo apt-get update && sudo apt-get upgrade
After that, the differents programs installed ans updated but libvirt-bin can't be configure by dpkg cause /etc/libvirt/qemu.conf don't exist.

Thanks for reporting this bug. Was /etc/libvirt/qemu.conf not existing on purpose?

Indeed the libvirt-bin.postinst should allow for that file not existing rather than fail package install.
