[lucid] libvirt-bin fails to install (sed: can't read /etc/apparmor.d/usr.bin.virt-aa-helper)

[Thierry Carrez]

Installing libvirt-bin on lucid, either manually or through the UEC/NC ISO installer, fails with:

Setting up libvirt-bin (0.7.2-4ubuntu3) ...
Adding group `libvirtd' (GID 114) ...
Done.
sed: can't read /etc/apparmor.d/usr.bin.virt-aa-helper: No such file or directory
dpkg: error processing libvirt-bin (--configure):
 subprocess installed post-installation script returned error exit status 2

I think the following postinst snippet should check for -n $2 before comparing, so that it doesn't fail in the "first install" case:

--
old_profile="/etc/apparmor.d/usr.bin.virt-aa-helper"
new_profile="/etc/apparmor.d/usr.lib.libvirt.virt-aa-helper"
if dpkg --compare-versions "$2" le "0.7.0-1ubuntu15"; then
    sed -i "s#/usr/bin/virt-aa-helper#/usr/lib/libvirt/virt-aa-helper#g" "$old_profile"
--

Instead of -n "$2", just use the le-nl operator in place of le.

This bug was fixed in the package libvirt - 0.7.2-4ubuntu4

libvirt (0.7.2-4ubuntu4) lucid; urgency=low
