No Linux fonts RPM packages were installed on the Linux CABI robot. The cabi server which is installed by the cabi probe requires the following set of fonts packages to be installed in order to be able to populate the contents of any UIM dashboard/report:
Release : 20.1
Component : UIM - CABI
OS: RHEL 7.6 (Primary hub + UMP and CABI robot)
Database: MySQL 5.7
Minimally install the fontconfig RPM package on the Linux RHEL robot:
yum install fontconfig
Then restart the CABI robot to force the cabi server to pick up the newly installed fonts packages.
