Install GroupDocs.Conversion for .NET on Linux Leave feedback

This article explains how to install and run GroupDocs.Conversion for .NET on a Linux-based system using .NET 6+. It also includes instructions for installing native dependencies that might be required when running in a headless environment.

Ensure the following tools and packages are installed:

• .NET 6.0 SDK or later: Install .NET on Linux
• A Linux distribution such as Ubuntu, Debian, CentOS/RHEL, or Alpine
• libgdiplus, fontconfig, and TrueType fonts

Ensure the multiverse repository is enabled:

sudo add-apt-repository multiverse
sudo apt update

Install the required packages:

sudo apt install -y libgdiplus fontconfig ttf-mscorefonts-installer

ttf-mscorefonts-installer is in the multiverse repository and downloads Microsoft fonts.

Enable EPEL repository and install required packages:

sudo yum install -y epel-release
sudo yum install -y libgdiplus fontconfig cabextract

To install Microsoft TrueType fonts:

wget https://downloads.sourceforge.net/project/mscorefonts2/rpms/msttcore-fonts-installer-2.6-1.noarch.rpm
sudo yum install -y msttcore-fonts-installer-2.6-1.noarch.rpm

Note: This method uses a third-party RPM for Microsoft fonts. You may need --nogpgcheck depending on your system configuration.

Install minimal dependencies using apk:

apk add --no-cache libgdiplus fontconfig ttf-dejavu

ttf-dejavu provides good font compatibility in Alpine.

In your project directory:

dotnet add package GroupDocs.Conversion
dotnet restore

Build and run your project:

dotnet run

• If you encounter System.DllNotFoundException, check if libgdiplus is installed.
• If fonts are missing or rendered incorrectly, verify fonts are present and accessible.
