我一直尝试在 ubuntu 18.10 中安装 Netflix 桌面，但使用以下命令没有成功
sudo add-apt-repository ppa:ehoover/compholio
sudo apt-get update && sudo apt-get install netflix-desktop
我收到以下错误。
E: The repository 'http://ppa.launchpad.net/ehoover/compholio/ubuntu cosmic Release' does not have a Release file.
N: Updating from such a repository can't be done securely and is therefore disabled by default.
N: See apt-secure(8) manpage for repository creation and user configuration details.
请帮忙
