[Pkg-virtualbox-devel] Bug#891860: virtualbox: Failed to preset unit: virtualbox-guest-utils.service

[Kevin Locke]

Package: virtualbox
Version: 5.2.8-dfsg-1
Severity: minor

Dear Maintainer,

During package installation, virtualbox, virtualbox-qt, and
virtualbox-source (and possibly other packages) print the following
error message if the virtualbox-guest-utils package is not installed
(and not being installed):

    Failed to preset unit: Unit file virtualbox-guest-utils.service does not exist.
    /usr/bin/deb-systemd-helper: error: systemctl preset failed on
    virtualbox-guest-utils.service: No such file or directory

Presumably the issue is that deb-systemd-helper should only be called
for virtualbox-guest-utils.service from the virtualbox-guest-utils
maintainer scripts, but is instead being called for all binary packages
from the same source package.

Thanks,
Kevin
