SYMPTOM
When running Strategy Intelligence Server 10.x on Linux, users may run into a situation wherein random symbols and shapes are seen in the graph legend/labels instead of legible characters as shown below:
CAUSE
One possible cause for this issue is that the font package liberation-mono-fonts is either not installed on the system or is unavailable to the Strategy Intelligence Server.
ACTION
Make sure liberation-mono-fonts package is installed on the system and that liberation fonts are available through font config as shown below:
fc-list | grep -i liberation Sample expected output: /usr/share/fonts/liberation/LiberationSerif-Italic.ttf: Liberation Serif:style=Italic /usr/share/fonts/liberation/LiberationSans-Bold.ttf: Liberation Sans:style=Bold /usr/share/fonts/liberation/LiberationMono-Bold.ttf: Liberation Mono:style=Bold /usr/share/fonts/liberation/LiberationSerif-BoldItalic.ttf: Liberation Serif:style=Bold Italic /usr/share/fonts/liberation/LiberationSerif-Regular.ttf: Liberation Serif:style=Regular /usr/share/fonts/liberation/LiberationSerif-Bold.ttf: Liberation Serif:style=Bold /usr/share/fonts/liberation/LiberationMono-Italic.ttf: Liberation Mono:style=Italic /usr/share/fonts/liberation/LiberationSans-BoldItalic.ttf: Liberation Sans:style=Bold Italic /usr/share/fonts/liberation/LiberationMono-Regular.ttf: Liberation Mono:style=Regular /usr/share/fonts/liberation/LiberationSans-Italic.ttf: Liberation Sans:style=Italic /usr/share/fonts/liberation/LiberationMono-BoldItalic.ttf: Liberation Mono:style=Bold Italic /usr/share/fonts/liberation/LiberationSans-Regular.ttf: Liberation Sans:style=Regular
