installing youtube-dl [SOLVED]

While installing mpv from synaptic, an older version of youtube-dl package was also installed. So, I uninstalled it and then ran these 2 commands to install the latest version:

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

I ran these commands and got this output:

~$ sudo curl -L yt-dl.org/downloads/latest/youtube-dl -o /usr/local/bin/youtube-dl

What should I do to install youtube-dl correctly?

(I can attach a screenshot if the above commands and their output is hard to read)
