Your Linux installation is too new :-).  We are working on a permanent solution.  For now, the workaround is to remove CHIMERA/lib/libfreetype.so* and CHIMERA/lib/libz.so*, where CHIMERA is the location Chimera was installed.  In your case, CHIMERA is /home/gwenny/.local/UCSF-Chimera64-1.12.     HTH,     Greg On 11/28/18 3:54 AM, Cackett, Gwenny wrote:

Hi so I am running Linux Fedora 29 and since updating from Fedora 28 I have noticed my Chimera installation has stopped working - the icon does not open the program. And when I try to run from the command line I get the code below, which I gather is an issue with python importing a module:

Any help would be appreciated. Thanks and best wishes,
