rosbuild and roslib are non existent packages and rosdep cant find (missing resource)

edit

I'm new to linux and ROS. if i've left out any key info needed to fix the issue, please let me know

I'm using debian 11 (Bullseye). I installed ROS through the following package deb file : https://debian.pkgs.org/11/debian-mai...

So far everything works well. I've setup a catkin workspace and have made and built a package. However the dependancies for some source files cant be found: 'rosbuild and 'roslib'.

invictus@INVICHOST:~$ rospack depends beginner_tutorials 

[rospack] Error: package 'rosconsole' depends on non-existent package 'rosbuild' and rosdep claims that it is not a system dependency. Check the ROS_PACKAGE_PATH or try calling 'rosdep update'
[rospack] Error: package 'rospy' depends on non-existent package 'roslib' and rosdep claims that it is not a system dependency. Check the ROS_PACKAGE_PATH or try calling 'rosdep update'

roscpp_traits
roscpp_serialization
catkin
genmsg

Trying to install via rosdep gives:

invictus@INVICHOST:~$ rosdep install roslib

ERROR: Rosdep cannot find all required resources to answer your query
Missing resource roslib
ROS path [0]=/home/invictus/catkinws/src

invictus@INVICHOST:~$ rosdep install rosbuild

ERROR: Rosdep cannot find all required resources to answer your query
Missing resource rosbuild

and doing rosdep update gives:
