You are using a custom cmake version (3.26 installed in ~/.local/lib/python3.8/site-packages/cmake). The default for Focal/Noetic is cmake 3.16.3 from /usr/bin/cmake. Are you using a python virtualenv?

[Kishor-Ramesh]

I am using windows WSL2 btw. what do you mean by python virtual environment? (sorry, i am not well versed with the terminologies as I am from a hardware background)

Plus, the default version for cmake is 3.26 when I completely ireinstall cmake.

[Kishor-Ramesh]

it builds upto 29 packages post which catkin fails to build

[Kishor-Ramesh]

sharing the error messages image as well just in case

[rhaschke]

How did you install cmake? I guess via pip. That's not the recommended way to manage a ROS system. Please follow the install instructions, which suggests rosdep to install required dependencies.

[rhaschke]

Probably your pip-installed cmake still works, but you are missing numpy now. Either try pip install numpy or use the recommended installation process.

[Kishor-Ramesh]

i used sudo apt install cmake

and I already have numpy installed. i even tried spcifiying the python3 path as flag to 'catkin_make'. but the error still occurs

i used the same link, yet the build failes at 'moveit_ros_planning_interface'

[rhaschke]

Probably you installed cmake via pip in the past then.

I used sudo apt install cmake

Where is cmake found? What is the result of which cmake? I guess, ~/.local/bin/cmake, which is wrong.

Obviously, you screwed your Ubuntu installation. If you are not able to recover, I suggest starting over and installing Ubuntu from scratch. Closing here as off-topic.

[Kishor-Ramesh]

how do I install cmake over again? and what should be the result of 'which cmake'?

[simonschmeisser]

It should start with /usr/

You can also check that your PATH and PYTHONPATH do not contain .local
