Hello,

[Problem]
=========

It looks like apt isn't able to resolve `dh-systemd | debhelper (>= 13.3)`. Whilst the line in logical and makes sense, that is, use dh-systemd for Groovy and older releases (since it's not present in Hirsute and thereafter) and use debhelper (...) for newer releases, et al.

However, apt is failing to resolve that for some reasons and it's thus results in FTBFS.

Some packages could not be installed. This may mean that you have

The following information may help to resolve the situation:

The following packages have unmet dependencies:
 sbuild-build-depends-main-dummy : Depends: dh-systemd but it is not installable
E: Unable to correct problems, you have held broken packages.
apt-get failed.
E: Package installation failed
Not removing build depends: cloned chroot in use

[Reproducer]
============

$ git ubuntu clone ubuntu-advantage-tools
$ cd ubuntu-advantage-tools
$ sbuild -s --source-only-changes

and that should yield a failed build.
