升级到 Ubuntu Zesty 17.04 后,我想安装一个很酷的壁纸,但是 apt-get 安装失败,并显示以下信息
W: GPG error: http://ppa.launchpad.net/realtime.sunlight.wallpaper/rsw/ubuntu quantal Release: The following signatures were invalid: 471A70A2000BD747ED3E0F6C15A8576D6E46FCAD
W: The repository 'http://ppa.launchpad.net/realtime.sunlight.wallpaper/rsw/ubuntu quantal Release' is not signed.
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.
我怎样才能手动签名并apt-get
始终忽略该警告?
谢谢任何线索!

如果只有一个或两个包文件(如果您尝试安装壁纸,可能会出现这种情况),那么我建议只从相应的 PPA 下载 deb 文件并使用以下方式安装它们
sudo dpkg -i <deb-file-name.deb>
命令。
