Hello,

npostavs on #emacs@freenode pointed me here.

I am running FreeBSD 12.0 and a master build from today (d5622eb from
2019-08-07) and also get: error in process sentinel: Staus: (:error
(error connection-failed "connect" :host "api.github.com" :service 443))

`list-packages' gives a similar error: error in process sentinel: Error
retrieving: https://elpa.gnu.org/packages/archive-contents (error
connection-failed "connect" :host "elpa.gnu.org" :service 443)
