Where can I get the Linux version of Unity Hub 3? The link on this page https://unity3d.com/get-unity/download goes to https://public-cdn.cloud.unity3d.com/hub/prod/UnityHub.AppImage, which is version 2

There will be no more official AppImages version of unity hub. Instruction to install the new version:
