You using an old version of youtube-dl [debug] youtube-dl version 2016.02.22 in the recent version it works as it should.
This issue should be closed.

Yep. Most likely it's an outdated package from Ubuntu. Hopefully more people can go to https://bugs.launchpad.net/ubuntu/+source/youtube-dl/+bug/1529647 and let the Ubuntu team know they shouldn't ship outdated youtube-dl packages.

[Ian-T-Price]

Er.... in that case ( and I do see the line in the --verbose report now ) I'd like to add to the bug report the fact that update does not work! When I had first had the error the first thing I did was to check versions and upgrade. See output below.

Knowing python, there's probably six different site-packages and the update is installed in the wrong one. I'll get back to you.

And yes, wrong version being picked up. /usr/bin/youtube-dl was first in the path but sudo pip install -U youtube-dl installed to /usr/local/bin/youtube-dl Strange that sudo installs to /usr/local

version 2017-10-29 does indeed work.

Thank you very much for your sterling work on this project and the rapid response to my issue.
And my sincerest apologies for troubling you with a non issue.
Many Thanks, Ian
