Hi all, I tried to compile a workspace using catkinmake for my ROS project. First I went to the home directory of linux system (Ubuntu 20.04) and create a new folder name Workspaces. Then I opened the Workspaces folder and create a new folder named **testws** under the workspaces. Then I created a new folder named src under the testws. Then I went to terminal and typed the command **cd Workspaces/testws/src/** to follow that path. Then I create a catkin package from the terminal following the command catkincreatepkg testpkg roscpp rospy stdmsgs sensor_msgs. Then I came back to home directory and entered to the test_pkg to create a folder named scripts. The test_pkg contained include, scripts, src, cmakeList.txt, and package.xml. After that I tried to compile the project using the command catkin_make. I got an error "Command 'catkin_make' not found, but can be installed with: sudo apt install catkin". Then I tried this command on terminal "~/Workspaces/test_ws$ source /opt/ros/foxy/setup.bash". Then tried "~/Workspaces/testws$ catkinmake". I again got the previous error. Then I tried "~/Workspaces/test_ws$ sudo apt install catkin" and get the following messages

Reading package lists... Done Building
dependency tree        Reading state
information... Done Some packages

that you have requested an impossible
situation or if you are using the
unstable distribution that some
required packages have not yet been

The following information may help to
 resolve the situation:

The following packages have unmet dependencies:
catkin : Depends: python3-catkin-pkg (>= 0.4.14-2) but it is not going to be installed
E: Unable to correct problems, you have held broken packages. 

After that I tried "~/Workspaces/test_ws$ sudo apt install ros-foxy-catkin". I received the following messages

Reading package lists... Done
Building dependency tree       
Reading state information... Done
E: Unable to locate package ros-foxy-catkin

Then I tried "sudo apt install ros2-foxy-catkin" I got following messages

Reading package lists... Done
Building dependency tree       
Reading state information... Done
E: Unable to locate package ros2-foxy-catkin

Then I updated the all using sudo apt update and ran the same commands again. The errors remained same. I tried all the solution that I found on web for this error but nothing worked.

I also checked the gcc version which produced "gcc (Ubuntu 9.4.0-1ubuntu1~20.04.1) 9.4.0 Copyright (C) 2019 Free Software Foundation, Inc."

Following is my ROS version "/Workspaces/testws$ echo $ROSDISTRO foxy "
