答案1

来自 steam repo文档：

下载steam.gpg并将其复制到/usr/share/keyrings/steam.gpg，例如：

sudo mv -v ~/Downloads/steam.gpg /usr/share/keyrings/steam.gpg

答案2

您必须重新添加过期的 GPG 密钥。打开终端并输入：

sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv-keys F24AEA9FB05498B7 531EE72F4C9D234C

然后使用更新包列表

sudo apt-get update

答案3

由于我尚无法编辑答案，因此我只能提出新的答案。

正如 N0rbert 所说，过期的 GPG 密钥必须重新添加。这可以通过执行以下命令来完成：

sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys F24AEA9FB05498B7 531EE72F4C9D234C

这通常应该可以解决问题。但是，还有另一个问题，因为这会将 Steam 的 GPG 密钥添加到/etc/apt/trusted.gpg，即使 Steam 的源文件 ( /etc/apt/sources.list.d/steam-stable.list) 指定查找/usr/share/keyrings/steam.gpg来源。可以通过执行以下命令修复此问题：

sudo apt-key export B05498B7 | sudo gpg --dearmour -o /usr/share/keyrings/steam.gpg

我遇到了同样的问题，这似乎解决了它。
