[Public] Iron PDF Docker Build Fails Due to xorg-x11-utils Conflict on Amazon Linux 2023

Description

When building a docker image targetting Amazon Linux 2023 (base image : public.ecr.aws/lambda/dotnet:8), the build may fail with a dependency conflict error related to xorg-x11-utils. This occurs because the pre-installed xproppackage obsoletes older versions of xorg-x11-utils, preventing successful installation with the following error:
problem with installed package xprop-1.2.7-1.amzn2023.x86_64 from amazonlinux obsoletes xorg-x11-utils < 7.5-39 provided by xorg-x11-utils-7.5-38.amzn2023.0.2.x86_64 from amazonlinux

Solution

The solution is to remove xorg-x11-utils from the list of Linux dependencies being installed in the Docker file with dnf install. The system already includes xprop, which covers its functionality.
