how to update software not in repo

[Valtam]

You need to reverse what ever method you installed it with in the first place. Then start fresh with this...

Code:

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

Then updates are simply..

Code:

sudo youtube-dl --update
