AttributeError: can't set attribute

[alexwpete]

I am attempting to migrate a ros1 package and all is going well for the exception of running the ros_upgrader.py:

I get an attribute error.

File "/home/ubuntu/ros2-migration-tools/porting_tools/cmake_lists_porter.py", line 391, in rule_replace_commands item.name = CatkinToAmentMigration.CMAKE_LISTS_REPLACED_COMMANDS[item.name]
Running Noetic ROS on focal Ubuntu with Python 3.8.10

I ran into the same issue. This seems to fix it for me:

I managed converting the CMakeLists.txt and package.xml.

Unfortunately, I ran into other issues creating the AST with libclang.
