Errors during transaction when installing QIIME2-2019.10

Hey @yanxianl,

Based on the first error message, it looks like something went wrong with the TLS handshake, sometimes that's because a server is misconfigured, your OS isn't up to date, or there's a firewall preventing access.

The three URLS being downloaded seem to be coming from different hosts (mostly)

So my guess is it's a firewall situation. Are you able to click and download those links manually, and do you see anything like a redirect when you do so?

That test doesn't help us install anything, but it'll help us figure out the network situation.
