Hey, I have been trying to download the audio from https://www.youtube.com/watch?v=vISSxIDytI0 and it wasn't working, so I tried to download the video and the audio and it still didn't work. I would suggest a way to fix it but I'm not really sure of a way you could. It works when i download the audio from other videos on youtube (i downloaded audio from https://www.youtube.com/watch?v=v1B80DsHwc8 just moments before) Here is the command and output:

[youtube] vISSxIDytI0: Downloading webpage

You are using an outdated version of youtube-dl. Read this FAQ entry if you have troubles updating.

@dstftw I was pretty sure I updated, but it turns out I forgot to add the PPA when I installed it, it's updating now and hopefully when it's updated it will work, thanks :)

Something else that also helps for Windows users and solved my problem: if you get Access denied upon updating it, go to the directory you have it installed in, and replace youtube-dl.exe with youtube-dl.exe.new. Something is preventing the new file from being copied to the old one.
