That means that the Ubuntu 22.04 container is running on top of an OS that has too old of a kernel. For example, RHEL/CentOS 7. ChimeraX needs a 3.11 kernel or newer. So, if you run the container on top of a newer version of Linux, like RHEL 8, you'd be fine. For an unsupported way to workaround the problem, see https://www.rbvi.ucsf.edu/pipermail/chimerax-users/2022-June/003880.html. If you are not using the GUI, then the workaround should be fine. If you are using the GUI, ChimeraX might crash in mysterious ways. HTH, Greg On 10/6/22 12:26, Hoover, David (NIH/CIT) [E] via ChimeraX-users wrote:
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:

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.
