英特尔Linux图形驱动程序

我想通过该程序安装英特尔Linux图形驱动程序,但每次我尝试安装它们时都会出现此错误

我该如何解决; 我真的想安装它,所以我可以玩Steam游戏。

你可以让ubuntu下载它抱怨的丢失密钥。

在您的情况下: ... the public key is not available: NO_PUBKEY 8D8847D52F4AAA66从错误消息8D8847D52F4AAA66复制哈希

 $ sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 8D8847D52F4AAA66 $ sudo apt-get update 

它不应该再抱怨了。
