2019.1.0f2 download failed through Hub

Open the Hub, and download 2019.1.0f2 ,but when it finished downloading and wait for installing, it poped an alert showed “download failed”. But when I installed the 2018 version, it worked.

Unity Hub version:1.4&1.5 both have the problem.

I’ve never got a successful installation through unity hub. I hate hub.
