为了能够从英特尔下载图形驱动程序,您必须将其 GPG 密钥添加到您的系统。否则,Ubuntu 将无法验证文件是否正确。
要添加密钥,请打开终端窗口并输入如下内容:
wget --no-check-certificate https://download.01.org/gfx/RPM-GPG-KEY-ilg \
-O - | sudo apt-key add -
或者
wget --no-check-certificate https://download.01.org/gfx/RPM-GPG-KEY-ilg-2 \
-O - | sudo apt-key add -
笔记英特尔似乎会定期更新其 GPG 密钥,并且他们的指示更新不频繁导致论坛帖子抱怨。但是,如果您不介意猜测的话,您会注意到上面两个键之间的差异已-2
附加到 URL。对于 16.04 的软件包,至少截至 2016 年 10 月 14 日,英特尔处于 状态-4
。我敢打赌下一个很可能是-5
