IMPORTANT: This affects Cvb v13.02.000 to v13.02.002 (on Jetson Nano).
Workaround steps (sudo is needed for all commands):
mkdir /opt/cvb/qt/lib
mkdir /opt/cvb/qt/lib/fonts
apt get install ttf-dejavu-core ttf-dejavu (these packages are typically already installed)
ln -s /usr/share/fonts/truetype/dejavu/DejaVuSans.ttf /opt/cvb/qt/lib/fonts/DejaVuSans.ttf
If you want a different font, just fill in the missing information:
ln -s /usr/share/fonts/<font family>/<font name>.ttf /opt/cvb/qt/lib/fonts/<font name>.ttf
