Comment 1 for bug 1702986

In terms of installation - it doesn't install straight properly on any of the releases unless dpkg is also backported.

See this from debhelper changelog:

  * Generate ddebs from debhelper instead of pkg-create-dbgsym (LP: #1623256)
    - Make debhelper Conflict/Replace pkg-create-dbgsym to force it off.
    - Revert the revert that disabled debhelper's attempts to do dbgsyms.
    - Mirror udeb code in dh_builddeb to allow us to alter file extension.
    - Set dbgsym Package-Type to ddeb to get correct debian/files output.
    - Depend on dpkg-dev (>= 1.18.23ubuntu3) so the above works correctly.
