Tested on Ubuntu20.04 The job can run. The heron-instance logs look good to me. Found some warning in heron-executor log: `RuntimeWarning: 'heron.instance.src.python.instance.st_heron_instance' found in sys.modules after import of package 'heron.instance.src.python.instance', but prior to execution of 'heron.instance.src.python.instance.st_heron_instance'; this may result in unpredictable behaviour` ``` [2020-08-06 23:01:57 +0000] [INFO]: Set up process group; executor becomes leader [2020-08-06 23:01:57 +0000] [INFO]: Register the SIGTERM signal handler [2020-08-06 23:01:57 +0000] [INFO]: Register the atexit clean up [2020-08-06 23:01:57 +0000] [INFO]: Start state manager watches [2020-08-06 23:01:57 +0000] [INFO]: Connecting to file state with rootpath: /home/ubuntu/.herondata/repository/state/local [2020-08-06 23:01:57 +0000] [INFO]: Registered state watch for packing plan changes with state manager <heron.statemgrs.src.python.filestatemanager.FileStateManager object at 0x7fe03de4d9d0>.
