Error The path to iptables is either not set or incorrect for IPTABLES [/sbin/iptables] in /etc/csf/csf.conf at line 26. Compilation failed in require at line 20. BEGIN failed–compilation aborted at line 20. Compilation failed in require at line 14. BEGIN failed–compilation aborted at line 14.

My System is Ubuntu 20.04

I Changed vi /etc/csf/csf.conf
To

IPTABLES = “/usr/sbin/iptables”
IPTABLES_SAVE = “/usr/sbin/iptables-save”
IPTABLES_RESTORE = “/usr/sbin/iptables-restore”
IP6TABLES = “/usr/sbin/ip6tables”
IP6TABLES_SAVE = “/usr/sbin/ip6tables-save”
IP6TABLES_RESTORE =

And still the problem exist !

When i excute: sudo csf -r
I recieve this error

Error Setting IPTABLES is repeated in /etc/csf/csf.conf - you must remove the duplicates and then restart csf and lfd at line 26.
Compilation failed in require at /usr/sbin/csf line 21.
BEGIN failed–compilation aborted at /usr/sbin/csf line 21.
