Guaranteed supported build for Ubuntu 20.04

[promistrio]

Hello!

What is the currently guaranteed supported build for Ubuntu? Which version of Unreal Engine and Airsim(Colosseum)?

First of all, I tried to build the latest version of Airsim c Unreal Engine 5.2. The engine showed an error and offered to rebuild in Visual Studio.

It also failed to build with version 5.0.3, because https://forums.unrealengine.com/t/upcoming-disruption-of-service-impacting-unreal-engine-users-on-github/1155880/31 and how to build version 5.0.3 now is not clear. Somethink like this.

UnrealEngine: Your branch is up to date with 'origin/5.0'. with latest commit in this repo

Hi @promistrio, Main branch is now supporting UE 5.1. There is no backward compatibility with 5.0.x and there are breaking changes in 5.2.

if I choose "skip convertion"

Same problem. after all installation process it doesnt work

[petergerten]

It would be great to have some more clarification on the actually supported engine version. I tried 5.3.1 as I was reading "now using Unreal Engine 5 version 5.03 or greater". But it results in compilation errors.

Then I saw "The main branch of this repository only supports Unreal Engine 5.2". So what exactly does this mean. Only "5.2" or also maybe "5.2.1"?

I have fix that few weeks ago lets imagine you have install Unreal Engine and clone Colosseum then you will face this error when you try to launch Colosseum thats because linux dont rebuild it automatically You need to go in folder where stored Block.uproject and double click on it, it will create .make file in that folder Using terminal in same folder you need to execute "make" it will generate necessery files and Colosseum will launch with unreal 5.2 without any problems
