Hi, one of our Build Servers (OSX) was running out of disk space while I was installing Unity 2019.4.0f1 on it. It ran out of space while moving the downloaded Unity.app, causing the installation to fail. The Hub however claimed, that the installation was successful and complete, causing our pipelines to fail because the executables for the Package Manager were missing (seemed like the runtime started, half of the Content/Resources/ Folder was missing. I'd suggest that the Hub checks and verifies the file signatures before claiming that an installation was successful. Thanks.
