Description

I was getting another error with the current version of yt-download, so I installed from the nightly:

sudo curl -L https://yt-dl.org/downloads/latest/youtube-dl -o /usr/local/bin/youtube-dl
sudo chmod a+rx /usr/local/bin/youtube-dl

This solved the error I was getting before, but introduced this new error, “Unable to extract uploader id”.
