Hey Guys,
You just installed LAMP on your Fedora and needs to restart iptables then this error message is always displayed.
[root@localhost enyamador]# systemctl restart iptables.service
Failed to issue method call: Unit iptables.service failed to load: No such file or directory.
This simple means you do not have iptables-services package installed.
Open Terminal and install:
# yum install iptables-services
Re-run command to restart iptables and it should pass successfully.
[root@localhost enyamador]# systemctl restart iptables.service [root@localhost enyamador]#
Hope it helps you.
