Description

I am running Ubuntu -19.10. I am trying to download all videos in the following playlist: "https://www.youtube.com/playlist?list=PL61035752268BE45B" but my download stops after 3rd video. I tried changing format to no avail. it throws warning ofHTML5 player then throws Signature extraction failure.. and it terminates.

Oh I am really sorry to trouble you with this false ticket! apparently my system was running old version in tab, had to restart the terminal fixed the issue. Thank you!
