Catkin_make error when downloading Baxter SDK

Question

Currently following this tutorial (http://wiki.lofarolabs.com/index.php/Baxter_Research_sdk_installation) to download Baxter SDK, when I reach the catkin_make section, i get this error:

Traceback (most recent call last): File "/home/rawnaa/ros_ws/src/baxter_interface/cfg/HeadActionServer.cfg", line 35, in from baxter_interface import settings File "/home/rawnaa/ros_ws/devel/lib/python3/dist-packages/baxter_interface/init.py", line 34, in exec(__fh.read()) File "", line 35, in File "/home/rawnaa/ros_ws/src/baxter_interface/src/baxter_interface/robot_enable.py", line 167 except OSError, e: ^ SyntaxError: invalid syntax make[2]: *** [baxter_interface/CMakeFiles/baxter_interface_gencfg.dir/build.make:144: /home/rawnaa/ros_ws/devel/include/baxter_interface/HeadActionServerConfig.h] Error 1 make[1]: *** [CMakeFiles/Makefile2:2876: baxter_interface/CMakeFiles/baxter_interface_gencfg.dir/all] Error 2 make: *** [Makefile:141: all] Error 2 Invoking "make -j2 -l2" failed

Im using ubuntu 20.04, ROS Noetic.

Not sure how to fix it, please help.

Many thanks

ROS Noetic changed to python 3 as the default version of python.

That error looks like the code that you're running is expecting python 2 style exceptions.

Looking at the tutorial it was written in 2015 for Ubuntu 12.04 or 14.04. at which time python 2 was the default.

To use software that old on a newer platform and version of ROS you will need to do a bunch of code migrations to upgrade the compatibility.
