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" -- ** Changed in: libvirt (Ubuntu) Importance: Undecided => High ** Changed in: libvirt (Ubuntu) Status: New => Triaged ** Also affects: libvirt (Ubuntu Lucid) Importance: High Status: Triaged -- [lucid] libvirt-bin fails to install (sed: can't read /etc/apparmor.d/usr.bin.virt-aa-helper) https://bugs.launchpad.net/bugs/493582 You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to libvirt in ubuntu. -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs
