Hi Steve, I thought, the error happened during configuration manager stage, while deploying ear or installing components.
however, even for LC installation, System fonts are mandatory for the installation. on Linux it will not be available by default, like we have in windows, system font at specified location. So system fonts are required to be setup. steps 2,3,4, of the above link of "system requirements-3.2.6.18" discuss setting up the mandatory packages and system fonts.
