[chimerax-users] Problems with Qt6

[Hoover, David (NIH/CIT) [E]]

Hi,

I'm trying to create a Ubuntu 22.04 container for ChimeraX v1.4 and no matter what I do I get this error message:

NOTE: Traceback (most recent call last):
   File "/usr/lib/ucsf-chimerax/lib/python3.9/runpy.py", line 197, in

  _See log for complete Python traceback._

I am attempting to install into Ubuntu 22.04 with ever Qt6 package available, but nothing seems to help.  The library in question definitely exists at /usr/lib/x86_64-linux-gnu/libQt6Core.so.6, along with a multitude of other libQt6* libraries.

Is there something additional that needs to be done or installed to enable ChimeraX v1.4 to run?  I have tried

   export LD_LIBRARY_PATH=/usr/lib/x86_64-linux-gnu:$LD_LIBRARY_PATH

but this does not help.  Any insight would be appreciated.

David
