BTW, the official unreal documentation uses ubuntu, Linux Game Development in Unreal Engine | Unreal Engine 5.1 Documentation
“Our development and support teams currently use the latest version of Ubuntu; as a result, we may not be able to provide support for other Linux distributions (including other versions of Ubuntu). Additionally, read about Hardware and Software Specifications , and make sure your system has at least one hundred (100) gigabytes of disk space before performing the following steps.”
So, does the development and support teams actually support what they claim to support?, who are them?, how can I contact them?
