Hi
It looks like you're missing dependencies.
Dpkg doesn't resolve dependencies on its own.

Try running
sudo apt-get -f install

This should install the missing dependencies.

Alternatively remove obs-studio and get the jammy Deb from 30.0.1 (code is the same) and install it with

sudo apt install ./foo.deb

We also offer a PPA
sudo add-apt-repository ppa:obsproject/obs-studio
sudo apt update
sudo apt install ffmpeg obs-studio

It's possible that the Deb from the CI build system is missing the dependency.

The package is called
qt6-wayland
You might need
qt6-qpa-plugins
as well

[hamirmahal]

Thanks for the detailed instructions. I'm trying them out now.

At this point, this is a support issue and not a bug. We are not currently accepting support requests on GitHub Issues. Please use our forums or Discord for further assistance.

Thank you!

[hamirmahal]

You're welcome! I understand.

[hamirmahal]

OBS Studio is able to start for me after running these steps that Gol-D-Ace posted above, so I'll just leave it here in case it helps anyone in the future.

sudo add-apt-repository ppa:obsproject/obs-studio
sudo apt update
sudo apt install ffmpeg obs-studio

I usually prefer opening issues like this on GitHub, because they're available to anyone, without an invite, and it can be more organized than several people asking questions at once in a Discord server. Plus, because it's public, it might be easier to find via a search engine, and I can also avoid registering for another forum.

[hamirmahal]

I'll look into using https://github.com/obsproject/obs-studio/discussions in the future. Thanks for the clear communication!

Ah, I didn't see that earlier. Thanks for pointing that out.
