Unable to locate package ros-humble-joint-state-publisher-gui
I am configuring my environment to seamlessly use ROS Humble distribution, but it feels like there is something to be debugged at every step.
I would like to run joint-state-publisher-gui and visualize my robot in rviz but it seems that gui has been segregated from the standard install unlike Foxy.
I am following the solution mentioned here - https://answers.ros.org/question/3449...
It could possibly be an issue that the source repository is not added, as per this - https://answers.ros.org/question/3466... and I did that as well in my Software Package Manager.
deb http://packages.ros.org/ros/ubuntu bionic main
Since I am using Ubuntu 20.04 and it has tier-3 support as per documentation.
It didn't solve my issue either. Then, I tried ignoring the ros-humble prefix altogether by using the commands
sudo apt-get install joint-state-publisher-gui
And surprisingly it did run and install a bunch of things including the joint-state-publisher

E: Unable to locate package ros-humble-joint-state-publisher-gui
However, still when I try to source the ros2 folder and try finding the joint-state-publisher-gui package, it's nowhere to be found. Kindly help in finding out what else I could be missing here.
EDIT - It definitely seems some sourcing issue is there. I am not able to install any Ros package. Not even this.
sudo apt install ros-humble-turtlesim
