Hi guys, after the upgrade to v16.01 I'm getting an error related to pbs-python when starting the job runners (the web runners seem fine). Here's the relevant part of the log file: galaxy.jobs.manager DEBUG 2016-05-10 15:52:49,972 Starting job handler galaxy.jobs INFO 2016-05-10 15:52:49,972 Handler 'job0' will load all configured runner plugins Traceback (most recent call last): File "/afs/igc.gulbenkian.pt/folders/UBI/SERVICES/GALAXY/galaxy_dist/lib/galaxy/webapps/galaxy/buildapp.py", line 63, in paste_app_factory app = galaxy.app.UniverseApplication( global_conf=global_conf, **kwargs ) File "/afs/igc.gulbenkian.pt/folders/UBI/SERVICES/GALAXY/galaxy_dist/lib/galaxy/app.py", line 150, in __init__ self.job_manager = manager.JobManager( self ) File "/afs/igc.gulbenkian.pt/folders/UBI/SERVICES/GALAXY/galaxy_dist/lib/galaxy/jobs/manager.py", line 23, in __init__ self.job_handler = handler.JobHandler( app ) File "/afs/igc.gulbenkian.pt/folders/UBI/SERVICES/GALAXY/galaxy_dist/lib/galaxy/jobs/handler.py", line 32, in __init__ self.dispatcher = DefaultJobDispatcher( app ) File "/afs/igc.gulbenkian.pt/folders/UBI/SERVICES/GALAXY/galaxy_dist/lib/galaxy/jobs/handler.py", line 723, in __init__ self.job_runners = self.app.job_config.get_job_runner_plugins( self.app.config.server_name ) File "/afs/igc.gulbenkian.pt/folders/UBI/SERVICES/GALAXY/galaxy_dist/lib/galaxy/jobs/__init__.py", line 671, in get_job_runner_plugins rval[id] = runner_class( self.app, runner[ 'workers' ], **runner.get( 'kwds', {} ) ) File "/afs/igc.gulbenkian.pt/folders/UBI/SERVICES/GALAXY/galaxy_dist/lib/galaxy/jobs/runners/pbs.py", line 94, in __init__ assert pbs is not None, PBS_IMPORT_MESSAGE AssertionError: The Python pbs-python package is required to use this feature, please install it or correct the following error: ImportError /afs/igc.gulbenkian.pt/folders/UBI/SERVICES/GALAXY/galaxy_dist/.venv/local/lib/python2.7/site-packages/pbs/_pbs.so: undefined symbol: job_log_mutex Removing PID file /var/run/galaxy/galaxy-job0.pid Any ideas on how to solve this?
