In an attempt to fix this i tried purging yt-dlp but was met with the following error :

```
E: Unable to locate package yt-dlp recipie.txt
```

** Although (purge yt-dlp) works fine but reinstalling etc. has no effect the problem persists.

For the first issue, it seems like you are hitting https://github.com/yt-dlp/yt-dlp/issues/6247 which was fixed in yt-dlp 2023.02.17 and above. If you'll note your 'apt-cache policy' output, there's a version higher than that ready to install, simply select it with `sudo apt install -t jammy-backports yt-dlp`.

For the second issue, apt returns the error "E: Unable to locate package yt-dlp recipie.txt" which shows you passed it "yt-dlp recipie.txt" as the package name, which obviously isn't correct. Correct your command for removal and it should work.

Lastly, pip can interfere with system installed packages, since you are mixing package managers. I believe generally you're advised to use venvs instead. If using pip and it breaks your system packages, you get to keep both pieces.

Thank you for taking the time to report this bug and helping to make Ubuntu better. Please execute the following command only once, as it will automatically gather debugging information, in a terminal:

apport-collect 2024967

When reporting bugs in the future please use apport by using 'ubuntu-bug' and the name of the package affected. You can learn more about this functionality at https://wiki.ubuntu.com/ReportingBugs.

I've marked this report as 'incomplete', you can return status to 'new' once apport-collect has been run on your impacted box & details can be seen.

For help on using backports (to get newer packages), please use a support site of your choice. I suspect a Support site would be more appropriate, eg. https://answers.launchpad.net/ubuntu. You can also find help with your problem in the support forum of your local Ubuntu community http://loco.ubuntu.com/ or asking at https://askubuntu.com or https://ubuntuforums.org, or for more support options please look at https://discourse.ubuntu.com/t/community-support/709
