I know this issue was discussed here and here . However, even after upgrading apt, I was still not able to install ROS Humble. I have tried the methods to fix this issue mentioned in the posts above but none of them work. Here is my Ubuntu version:

LSB Version:    core-11.1.0ubuntu4-noarch:security-11.1.0ubuntu4-noarch
Distributor ID: Ubuntu
Description:    Ubuntu 22.04.1 LTS
Release:    22.04
Codename:   jammy

Here is how the error pops up :
