You can find the Debian version of installed and candidate package with
'apt-cache policy <pkgname>'. The version of systemd in stretch is
232-25+deb9u1. If your attempt to install libsnmp-dev resulted in that
error message, then it is likely that you have not upgraded your
packages since prior to the stretch release.

Please supply the output of 'apt-cache policy libsnmp-dev systemd' and
the contents of your sources.list.
