Is this all there is in the error message? It should be followed up by instructions to try to update youtube-dl and then, if the problem persists, post the entire output of youtube-dl when called with -v.

I am closing this issue now since I suspect that simply using a current version of youtube-dl will fix this. If the problem persists with the current version, please post the entire output you get when running youtube-dl with -v, and we will reopen this issue. Thanks!
