Not resolved yet, but a bit more info.

Here are the results on len4, where the yt-dlp update was successful:
ll@len4:~$ dpkg -l yt-dlp
dpkg query: no packages found matching yt-dlp
ll@len4:~$ 

Here are the results on leno, not yet working:
ll@leno:~$ dpkg -l | grep -i yt-dlp
ii yt-dlp 2023.03.04-1~bpo11+1 all downloader of videos from YouTube and other sites
ll@leno:~$

Additionally, I got more familiar with dpkg and grep from https://www.debian.org/doc/manuals/debian-faq/pkgtools.en.html and https://www.howtogeek.com/496056/how-to-use-the-grep-command-on-linux/

Here's the situation:
The most recent version, 2023.07.06, is working on len4.
However, the old verion, 2023.03.04, on leno, results in the http 403 forbidden error and fails to download any videos. Until recently, yt-dlp was working on both.

How can I get yt-dlp to work again on leno?

In gratitude,
LeRoy

In that first vignette you have stuff likely installed with pip, but it looks like someone unwisely ran pip as root instead of using the --user option.

So that's where pip will give you the latest.

Note that you should make sure that you have $HOME/.local/bin in your path when you install stuff with pip, and that you use the --user option.

In the second vignette you have it as a system package, which might update more slowly.  You can remove that and then install your own.  Removing system packages is done with "sudo apt remove pkgname" on debian and "sudo dnf remove pkgname" on rpm-based systems.

To confirm even more that it's from a system package you can do:

dpkg -l | grep -i yt-dlp   # (debian-based)

rpm -qa | grep -i yt-dlp   # (redhat-based)
