Cannot upgrade docker Ubuntu

Description:
I cannot use the command of iptables due to the ubuntu kernel upgrade error in Docker.

Steps:

Step 1. I tried the command below. But the error message below appears.

$$ iptables -L

iptables v1.6.1: can’t initialize iptables table `filter’: Permission denied (you must be root)
Perhaps iptables or your kernel needs to be upgraded.

Step 2. To solve the issue, I tried the command below. But the error below appears.

$$ apt-get install linux-image-$(uname -r)
