youtube-dl: SSL certificate verify failed

#4807 was diagnosed on FreeBSD. As suggested, I’m reporting the same issue on ArchLinux.

However, I’ve installed youtube-dl through nix, you may want to investigate as if I were running NixOS.

Did you try using ‘–no-check-certificate’ as a temporary workaround?

FYI - to fix this please see https://stackoverflow.com/a/42334357/1896134

This seems to be a problem for 3.6 & 3.7 details listed in the SO answer.

In short, try this

pip3 install certifi Then /Applications/Python\ 3.7/Install\ Certificates.command

Your terminal should look something like this:

$ pip3 install certifi

After installing python3 and python 2 with nix (on OSX), with the latest version of youtube-dl --no-check-certificate seems to be fixed. If you set and export the variable SSL_CERT_FILE to the path of your CA bundle (if you installed the cacert package, you can use ~/.nix-profile/etc/ca-bundle.crt), the CA certificates are properly loaded and --no-check-certificate is not needed.

I’ve encountered the same problem. Installed youtube-dl with pip3 install youtube-dl

Then got the error when I did : sudo youtube-dl [URL]

ERROR: Unable to download webpage: <urlopen error [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed (_ssl.c:749)> (caused by URLError(SSLError [3] Exit 1 sudo youtube-dl https://www.youtube.com/watch?v=19ecwVEvI-0

Fixing the command to sudo youtube-dl --no-check-certificate https://www.youtube.com/watch?v=19ecwVEvI-0&feature=youtu.be&app=desktop solved my problem. I was running the code on Mac OS
