This is an issue with 'fonts' on the server and can occur if certain font packages are not installed or existing font packages need to be updated.
This may happen if the minimum installation option is chosen when installing the operating system.
The installing or updating of fonts is an Operating System administration issue and not an issue with ESM.
Run this command to find out what dejavu fonts and fontconfig software you have installed (Redhat/CentOS):
rpm -qa | grep -e dejavu -e fontconfig
Please consult with your operating system administrator for assistance sourcing and installing these packages.
The following is a suggestion on how these packages could be installed:
If the operating system is configured to use "yum" with the necessary proxies and repositories, you can use yum commands to install the necessary software:
yum install fontconfig
yum install dejavu*
If you do not have the necessary respositories configured, then you can alternatively download the packages from official Internet sources for your operating system vendor.
