NetWorker: Enabling networker.service on Linux returns an error

When enabling networker service using below command:

It returns an error.

systemctl enable networker

The error returned is:
 

 Synchronizing state of networker.service with SysV service script with /usr/lib/systemd/systemd-sysv-install.
 Executing: /usr/lib/systemd/systemd-sysv-install enable networker
 Failed to execute /usr/lib/systemd/systemd-sysv-install: No such file or directory

The error when enabling networker.service might occur because the service file is not located in the default directories that systemctl searches.
The service is not recognized by its short name if it does not adhere to standard naming conventions.
Furthermore, the error message indicates that systemd-sysv-install is missing, which is necessary for compatibility with SysV init scripts, suggesting that the service might not be fully compatible with systemd without specifying the full path.

Run the command by specifying the full path to the service unit:

# systemctl enable /usr/lib/systemd/system/networker.service
