Not the Fedora package, no. "nut" contains the core server components. > Not at a computer now, but I think Debian and OpenIndiana packages were > grouped this way.

Yes, looks like they have: nut/bionic,bionic 2.7.4-5.1ubuntu2 all - metapackage nut-cgi/bionic 2.7.4-5.1ubuntu2 amd64 nut-client/bionic 2.7.4-5.1ubuntu2 amd64 nut-doc/bionic,bionic 2.7.4-5.1ubuntu2 all nut-ipmi/bionic 2.7.4-5.1ubuntu2 amd64 nut-monitor/bionic,bionic 2.7.4-5.1ubuntu2 all nut-server/bionic 2.7.4-5.1ubuntu2 amd64 nut-snmp/bionic 2.7.4-5.1ubuntu2 amd64 nut-xml/bionic 2.7.4-5.1ubuntu2 amd64 And installing nut-server gets you: The following additional packages will be installed: libupsclient4 nut-client Suggested packages: nut-monitor nut-cgi nut-ipmi nut-snmp nut-xml The following NEW packages will be installed: libupsclient4 nut-client nut-server Interesting that the monitor is a separate package from client.
