My iptables version is v1.6.1. How can I upgrade it?
I tried:
root@ubuntu:~# apt update iptables
E: The update command takes no arguments
root@ubuntu:~#b apt upgrade iptables

iptables is already the newest version (1.6.1-2ubuntu2).

The following packages were automatically installed and are no longer required:
libshishi0 linux-aws-5.4-headers-5.4.0-1037 linux-aws-5.4-headers-5.4.0-1038 linux-aws-5.4-headers-5.4.0-1039
linux-aws-5.4-headers-5.4.0-1041 linux-aws-5.4-headers-5.4.0-1043 linux-aws-5.4-headers-5.4.0-1045
linux-aws-5.4-headers-5.4.0-1047 linux-aws-5.4-headers-5.4.0-1048 shishi-common tcpd
Use 'apt autoremove' to remove them.
The following packages have been kept back:
docker-ce
0 upgraded, 0 newly installed, 0 to remove and 1 not upgraded.
But after that, I checked the version and it still v1.6.1.
