    virtual camera stop working in OBS after upgrading to Ubuntu 21.04

    Not sure if the install of Ubuntu 21.04 removed something needed to run the virtual camera in OBS. After upgrade it installed OBS 26.1.2 so I did
    Code:
    sudo rm /etc/apt/sources.list.d/btbn*
    But it could not find it to remove it. Then I did a
    Code:
    sudo add-apt-repository ppa:obsproject/obs-studio
    Code:
    sudo apt-get update
    Code:
    sudo apt-get purge obs-*
    Code:
    sudo apt-get install obs-studio
    I am now at OBS Studio 27.0.1 I still have the button for
    Start Virtual Camera
    But it will not work. My question is: Is there something I am still missing? The way I ran the purge it should have removed obs-plugins and then reinstall them
    Just for the record, I am not using "Wayland" but "xorg."

    Re: virtual camera stop working in OBS after upgrading to Ubuntu 21.04

    I found this:
    Bad News, Everyone!
    As of 2021-07-02, upgrading to Ubuntu (or Pop!_OS) 21.04 creates a problem with the Virtual Camera feature of OBS Studio. Fortunately, there is a workaround that’s only very mildly annoying.

    I’m experiencing the problem in this issue: https://github.com/obsproject/obs-studio/issues/4808.

    I work around the problem by doing the following:

    Exit OBS Studio.
    $ sudo modprobe -r v4l2loopback
    Launch OBS Studio.
    Press Start Virtual Camera.
    If I stop the Virtual Camera, then I need to repeat these steps in order to restart it. Not so bad. I wish the OBS Studio team well in fixing the problem; I wish I knew enough to be able to help.
    and it works, but not a good way to do this.
