on systems controlled by systemd, the knockd service will never start because it is not possible to enable it. [test case] install a system that uses systemd, and install knockd package. try to enable the service: $ sudo systemctl enable knockd Synchronizing state of knockd.service with SysV service script with /lib/systemd/systemd-sysv-install. Executing: /lib/systemd/systemd-sysv-install enable knockd The unit files have no installation config (WantedBy, RequiredBy, Also, Alias settings in the [Install] section, and DefaultInstance for template units). This means they are not meant to be enabled using systemctl. Possible reasons for having this kind of units are: 1) A unit may be statically enabled by being symlinked from another unit's .wants/ or .requires/ directory. 2) A unit's purpose may be to act as a helper for some other unit which has a requirement dependency on it. 3) A unit may be started when needed via activation (socket, path, timer, D-Bus, udev, scripted systemctl call, ...). 4) In case of template units, the unit is meant to be enabled with some instance name specified. after fixing the knockd.service file, the service can be enabled: $ sudo systemctl enable knockd.service Synchronizing state of knockd.service with SysV service script with /lib/systemd/systemd-sysv-install. Executing: /lib/systemd/systemd-sysv-install enable knockd [regression potential] very low, as knockd is useless currently since it can never be started from systemd. any regressions would be in the area of starting knockd. [other info] the systemd service for knockd also needs the fix from bug 1819345 this applies only to b/c/d since t/x use upstart to manage services, and this problem is only in the knockd systemd service file. original description: --- About my Ubuntu: Description: Ubuntu 18.04 Release: 18.04 About Knockd: knockd: Installed: 0.7-1ubuntu1 Candidate: 0.7-1ubuntu1 Version table: *** 0.7-1ubuntu1 500 500 http://archive.ubuntu.com/ubuntu bionic/universe amd64 Packages 100 /var/lib/dpkg/status >>>>>>>>>> When enabling knockd with systemctl y get the following error: ### $ sudo systemctl enable knockd Synchronizing state of knockd.service with SysV service script with /lib/systemd/systemd-sysv-install.
