Doesn't work and has a script problem

[BSDsEnjoyer]

Hello, I really like the idea of this, but the script is bad and the video does not download from youtube.

The script updates ALL packages on my system - is this really necessary to update thunderbird email system to watch Bad Apple in terminal? Now I wonder whether this broke anything... Well more for me to learn about running scripts from the internet.

After running install.sh successfully I could not load the video from youtube, it gave an error:

ERROR: unable to download video data: HTTP Error 403: Forbidden

I really suggest to not use youtube or other corporate platforms to host the video, maybe it could be reuploaded somewhere else, or, even better, added into a package?
