I followed instructions, but go error as follows:

Now installed obs-studio using apt and now installed setting up plugins gives the first error. How to fix it?? Any help

From #52:

sudo apt install libobs-dev

Hope this helps!

Above command give me the following error, but i have managed it this time.
The following packages have unmet dependencies:
libobs-dev : Depends: libobs0 (= 25.0.3+dfsg1-2) but it is not going to be installed

sudo apt install libobs0
sudo apt install libobs-dev

Thanks Bro Arii
