Hi,
I’m looking for Unity 2018.4.x editor for Linux. Is there any link I could download it? I need UnitySetup executable.
I was looking at releases and announcements thread and I can only find 2018.3.x and 2019.1.x versions.
Please don’t point me to Unity Hub - I need to install Unity on Docker container for running tests, I would like to omit the step where I have to configure some access to X11 just to select version.
Let me know if you’re successful. I was unable to get it working when I tried, but that was quite a while ago. That said, last I checked, you won’t be able to activate a license from the command line, so afaik you’ll still need brief X11 access. Somebody might correct me if I’m wrong, but that was the case when last I tried to use Docker for testing. On the other hand, it was something about Jenkins that wouldn’t cooperate once I had the editor activated.
I have 2018.1 running on Jenkins in Docker 
Hardest part was to figure out permission issues - Jenkins runs as jenkins. Most non-obvious thing was setting HOME variable when starting Unity, so that jenkins reads license from the correct directory. Also, you need to set up proper file ownership.
All my Jenkins invocations I start with:
export HOME=/home/jenkins
To do license activation I used instructions from: GitHub - game-ci/unity3d-gitlab-ci-example-mirror: 🍴Mirror of the game-ci/unity3d-gitlab-ci-example project. If you are looking for Github Actions, refer to https://game.ci/ documentation instead (b. Locally)
Luckily it didn’t require me to run X11.
