Installing Additional Fonts for Collabora

By default, Collabora Online provides only a limited set of fonts.
To ensure proper document rendering — especially for Microsoft Office documents — you may want to install additional font packages such as ttf-mscorefonts or other TrueType/OpenType fonts on your server.

1. Access the Server and Update System Packages

Before installing new fonts, make sure your system packages are up to date:

apt update

2. Install Microsoft Core Fonts

Install the Microsoft Core Fonts package to add common fonts such as Arial or Comic Sans MS:

apt install ttf-mscorefonts-installer

During the installation, you will be prompted to accept the EULA (End User License Agreement).

3. Restart Collabora

After the installation is complete, restart your docker-compose setup to apply the changes:

docker compose restart

Once restarted, Collabora will recognize the newly installed fonts, and they will be available when editing documents.
