Hello, On a Ubuntu 18.04.1 LTS, I get this error message when I start chimera. Is there a known fix? Am I running a too old version of chimera or should I run a version specially compiled for Ubuntu computers? Here is the full error message: --- # chimera Error while importing plipgui from /home/berenger/.local/lib/python2.7/site-packages: Traceback (most recent call last): File "/home/berenger/usr/chimera-1.12/share/chimera/extension/base.py", line 349, in _importExtension __import__(module) File "/home/berenger/.local/lib/python2.7/site-packages/plipgui/ChimeraExtension.py", line 8, in <module> from plipgui.core import cmd_plip, cmd_unplip File "/home/berenger/.local/lib/python2.7/site-packages/plipgui/core.py", line 50, in <module> from plip.modules.preparation import PDBComplex File "/home/berenger/.local/lib/python2.7/site-packages/plip/modules/preparation.py", line 13, in <module> from .detection import * File "/home/berenger/.local/lib/python2.7/site-packages/plip/modules/detection.py", line 12, in <module> from .supplemental import * File "/home/berenger/.local/lib/python2.7/site-packages/plip/modules/supplemental.py", line 26, in <module> import pybel File "/home/berenger/.local/lib/python2.7/site-packages/pybel.py", line 53, in <module> import openbabel as ob File "/home/berenger/.local/lib/python2.7/site-packages/openbabel.py", line 21, in <module> _openbabel = swig_import_helper() File "/home/berenger/.local/lib/python2.7/site-packages/openbabel.py", line 20, in swig_import_helper return importlib.import_module('_openbabel') File "/home/berenger/usr/chimera-1.12/lib/python2.7/importlib/__init__.py", line 37, in import_module __import__(name) ImportError: /home/berenger/usr/chimera-1.12/lib/libgomp.so.1: version `GOMP_4.0' not found (required by /usr/lib/libopenbabel.so.4) --- Thanks a lot, F.
