Start with the linux.service action and the generated /tmp/5f191803f06137c07014deb2/service.py at line 23, where it imports st2common.util.shell. Reproduce the shown st2 run command and inspect why that module is unavailable in the action runtime. Done means the action runs without this ImportError.
