Issue with HTTP/2 and async file upload from Safari on iOS

[ZaneCEO]

Hi guys,
that's the issue for me: I'm with Ubuntu 16.04 official packages. I apt
dist-upgrade, but still I'm on nginx/1.10.0..

Any solution other than switching to
https://launchpad.net/~nginx/+archive/ubuntu/development (wich scares the
skull out of me, since this is a production server)?
