Document Exporter for Cameo Collaborator requires Microsoft TrueType fonts to be installed on the server. Otherwise, PDF/HTML document export will fail. Alternative font packages, such as dejavu-serif-fonts, provide support for TrueType fonts and will work with Document Exporter. However, only Microsoft TrueType font will guarantee that the exported document retains original document formatting. 

Prerequisites

  • EPEL package repository must be installed and enabled.
  • cabextract package must be installed from EPEL repo.

General method for installing font package

The steps provided here describes a universal method for installing the Microsoft TrueType font package on a Linux system. An online staging environment is required if installing on an air-gapped system.

To install the Microsoft TrueType font package:

  1. Download font installer package to a predefined working path and extract:
    WORK_PATH=/opt/local/install/temp
sudo mkdir -p $WORK_PATH && cd $WORK_PATH
wget  https://phoenixnap.dl.sourceforge.net/project/mscorefonts2/sources/msttcore-fonts-installer-2.6.tar.gz
tar --strip-components=4 -xzf msttcore-fonts-installer-2.6.tar.gz -C $WORK_PATH msttcore-fonts-installer-2.6/usr/lib/msttcore-fonts-installer/
sudo mkdir -p $WORK_PATH/msttcore-fonts
./refresh-msttcore-fonts.sh -d $WORK_PATH/msttcore-fonts
  2. Verify font extraction and generate the font package for installation:
    ls -la $WORK_PATH/*.ttf
sudo pushd $WORK_PATH/msttcore-fonts && tar -cvzf $WORK_PATH/msttcore-fonts.tar.gz *.ttf && popd
  3. If installing to an air-gapped environment, copy font package to the Document Exporter server.
  4. Install fonts to the server and verify installation:
    sudo mkdir -p /usr/share/fonts/msttcore
tar -xzf msttcore-fonts.tar.gz -C /usr/share/fonts/msttcore/
