Am I seeing this correctly?
According to documentation AIFabric v2020.4 is still supported Ubuntu 20.04 LTS (source: https://docs.uipath.com/ai-fabric/v2020.4/docs/software-requirements) but the new 2020.10 AIFabric is only supported on Ubuntu 18.04 (source: https://docs.uipath.com/ai-fabric/docs/ai-fabric-singlenode-requirements)
This is quite unfortunate.
Cheers,
