Description of your issue, suggested solution and other information

I updated brew and upgraded youtube-dl but this does NOT provide the latest version so I ran youtube-dl -U as root and it fails.

Seems a network issue. Could you try to open https://yt-dl.org/downloads/2017.08.27.1/youtube-dl in browsers (Safari, Chrome, Firefox, etc.) and see if the file can be downloaded or not?

[ballo]

Appears to be fine with wget. youtube-dl doesn't appear to even attempt it. It downloads the initial file with the version but after that I see no activity with packet sniffers

Thanks for the feedback.

I see no activity with packet sniffers

youtube-dl tries to fetch the new binary but apparently it fails at the DNS step. Did you see packets on UDP 53 port?

By the way, I just tried it on Sierra (Darwin-16.7.0-x86_64-i386-64bit) and -U works just fine. Not sure is it related to macOS internal changes or not.

[ballo]

Did you install it using brew? I'm using OS X 10.10.5. If you install from brew you don't get the latest version.

I don't see how python would be different than wget in terms of DNS resolution. I tried deleting the dns cache just in case but predictably that didn't help.

[ballo]

Hm, maybe it did help. Seems to be downloading now

[ballo]

OK, I think I had some kind of DNS cache issue. Attempting to close this...
