Unable to update - HTTP Error 404: Not Found

[Rosuav]

Trying to download any video from Youtube results in "KeyError: 'sig'", so I'm trying to update youtube-dl to see if there are any changes.

$ sudo youtube-dl --updateUpdating to latest version...

$ youtube-dl --version

Am I on a version that's too old to automatically update? If so, what's the recommended approach?

See #3149 for a manual update method:

wget https://yt-dl.org/latest/youtube-dl -O ./youtube-dl

[Rosuav]

Ah, and more importantly #3152 which mentions the lack of SNI.

(Does this really need to be downloaded via https?)
