OK. Still, I have no problem changing the version. Do you recommend it?
Which version?
Ubuntu from 18.04. to 22.04?
I would first test to install Sinusbot new if it's not working at all, if it's working with music like uploaded tracks or radio streams then I only would test the yt-dlp how to get it to work.
If you have nothing really necessary on the server, I would update it to the new version but eventually with a complete new installation.
I made a major upgrade from an old version to a new one and many software packages had old dependencys and other problems.
I had not that big issue with that. But you have do to a little work before you update a major version.
But for me I got a new server with the new install and the other were deleted. For that I didn't had to deal with the issues.
I don't know your complete setup or environment, I can't help you exactly with what is wrong or not working. You have to check logs and so on.
For me, as said, it was really easy to install yt-dlp
