Have an errror Could neither find file "toplevel.cmake" on Ubuntu 20.04

edit

Try to catkin_init_workspace in directory ~/catkin_ws/src, but have an error:

Could neither find file "toplevel.cmake" in any workspace nor relative, checked the following paths:

/home/mvshalamov/catkin_ws/src/catkin/cmake/toplevel.cmake

/usr/local/lib/python3.8/cmake/toplevel.cmake

/usr/local/share/catkin/cmake/toplevel.cmake

/usr/local/lib/share/catkin/cmake/toplevel.cmake

I checked there is no toplevel.cmake in any of these directories. I also tried sudo mv share /usr/local/lib but there is not catkin in it.
