Can't install powershell_es

Hello! Ah hmmm Windows issues.. Are you perhaps behind some sort of proxy?

[sakhnik]

No proxy, direct access. I tried the advice from http://vcloud-lab.com/entries/powershell/powershell-invoke-webrequest-the-request-was-aborted-could-not-create-ssl-tls-secure-channel, added it to $profile. No luck. But iwr https://github.com succeeds in the interactive shell. Also, I tried enabling wget from MinGW, but in vain.

[williamboman]

So the API that's causing this is GitHub's, which started refusing TLSv1/TLSv1.1 quite some time ago (2018). Let me do some research on iwr..

[williamboman]

Hey @sakhnik, could you try the branch fix-iwr-tls (#487) and see if it fixes things?

[sakhnik]

Sure it does, thanks!
