Hi,
when updating today I've seen the following in my apt logs:
Preparing to unpack .../grommunio-admin-api_1.17.33.0a2d18a-1+6.1_all.deb ...
Unpacking grommunio-admin-api (1.17.33.0a2d18a-1+6.1) over (1.17.32.021a23c-1+37.1) ...

Thank god dpkg did not delete the systemd file directory, but this should not be tried anyways. Can you please check the Debian package here.
