Package: youtube-dl
Version: 2016.02.22-1

When attempting to download from vimeo I am getting the following error:

========================================================================
$ youtube-dl https://player.vimeo.com/video/156377457
[vimeo] 156377457: Downloading webpage
[vimeo] 156377457: Extracting information
[vimeo] 156377457: Downloading JSON metadata
[vimeo] 156377457: Downloading m3u8 information
WARNING: Failed to download m3u8 information: <urlopen error [SSL:
CERTIFICATE_VERIFY_FAILED] certificate verify failed (_ssl.c:581)>
ERROR: unable to download video data: <urlopen error [SSL:
CERTIFICATE_VERIFY_FAILED] certificate verify failed (_ssl.c:581)>
========================================================================

This started maybe a week ago, maybe something changed with vimeo?

Thanks,

I don't know. Things work perfectly fine for me:

On the other hand, the error that you're seeing is *very* similar to the
error that some people have reported on a project of which I am upstream
(coursera-dl).

What version of Python are you using? I suspect that if you are using the
package from unstable on an earlier release, with Python 2.7.x with x < 9,
then that may be related with the bug that I'm seeing upstream.

If not, then I sincerely don't know. I plan on moving youtube-dl to Python
3 on my next upload and if I recall correctly, the SSL stuff in Python >=
3.4 works well (and was backported to late versions of Python 2.7).

Regards,

Yes I installed the unstable youtube-dl on jessie.

It would be nice to have a jessie backport (and maybe jessie update as has
been done in the past) that works, even if the backport requires a little
tweaking to the source package to make it work.

It seems that a fix to this problem may be installing the package
ca-certificates... Can anybody with the problem test it and report it back?
If so, then this bug should be merged with bug 819759...

Regarding a jessie backport, Antoine Beaupré created an appropriate bug
report (833865) and I hope that we can make frequent backports to the stable
distribution in a systematic way.

Hi,

I've confirmed that the video you mentioned can be downloaded with the
current version of youtube-dl in sid (which uses python3), hence closing
the bug report.

Daniel
