It seems this is related to this - #1421 (comment), I installed using PIP (Debian 7) which file to get from repo and where to put it ?

[EveryDirection]

Just chiming in to confirm the error, which I am seeing with nearly-identical verbose output about encrypted signature length 82, with other videos when using 2013.11.09.

Another example:

[Tatsh]

Same error here. Another signature length change. Tried with latest from repository.

[jaimeMF]

On Linux you can run make youtube-dl to build the executable with the latest version of youtube-dl, @Tatsh it should work with the repo version (if not, open a new issue with the output and the sha of the commit).
On Windows, running python setup.py py2exe will build youtube-dl.exe.
Unfortunately, we have problems with the build server (#1420 (comment)).

[Elite]

Thanks @jaimeMF , I am no Linux geek so pls. tell will make youtube-dl replace the PIP installed version ? If not will make install do the trick ?

[jaimeMF]

Yes make install will copy youtube-dl to /usr/local/bin, but you'll probably need to run it with sudo. But you'll probably want to do it manually (otherwise you'll need to build more things), with install -m 755 youtube-dl /usr/local/bin.
Note: if you run make youtube-dl and it says youtube-dl is up to date, then run make youtube-dl --always-make

[phihag]

You can now simply type sudo youtube-dl -U update (or sudo pip -U youtube-dl) to update to v2013.09.16, which contains the fix.
