我正在运行最新的Ubuntu 16.10桌面操作系统。
如何安装gtk-v4l包来控制我的网络摄像头设置？
我在期间收到以下错误apt-get update：
W: The repository 'http://ppa.launchpad.net/libv4l/ppa/ubuntu yakkety Release' does not have a Release file.
N: Data from such a repository can't be authenticated and is therefore potentially dangerous to use.
N: See apt-secure(8) manpage for repository creation and user configuration details.
E: Failed to fetch http://ppa.launchpad.net/libv4l/ppa/ubuntu/dists/yakkety/main/binary-amd64/Packages 404 Not Found
