Re: Problems with youtube-dl [solved]

Did you download the app via Synaptic? That might be the problem as the repo version is too old to work with youtube videos. I download the app straight from their website (using wget) which gives you the current version:

Re: Problems with youtube-dl [solved]

I have had good luck with python-pip on this very "ERROR: Signature extraction failed:" issue.  As Ron states, I believe its an out of date/update problem with youtube-dl.  python-pip is a method to upgrade your existing youtube-dl.

This needs to be installed once, to install pip:

apt-get install python-pip

Then run this command to upgrade youtube-dl, and also run this command when you get the "ERROR: Signature extraction failed:"  error in the future

pip install --upgrade youtube-dl

Re: Problems with youtube-dl [solved]

As a test, I attempted your download:

youtube-dl https://www.youtube.com/watch?v=i3JPUobdDm8

And received the error.  I then updated my youtube-dl:

pip install --upgrade youtube-dl

Then tried the download again and it worked fine.
