适用于 Linux* OS v2.0.2 的英特尔显卡更新工具无法更新显卡驱动程序

  • 772

我下载了用于更新驱动程序的英特尔图形工具并收到以下错误：

Ensuring consistent system... OK
Listing packages... OK
Setting up repositories... OK
Installing packages...
    Updating package cache... Failed

错误详情：

有谁知道如何修理它？

操作系统：Ubuntu 16.04 LTS
显卡：Intel® Iris Pro Graphics 580 (Skylake GT4e)

谢谢，

    Ubuntu 16.04 带有相当更新的英特尔显卡驱动程序。英特尔 PPA 必须提供的次要修订更新几乎没有什么好处。

    也就是说，如果您仍然想使用该工具，那么您应该按照下载页面上的所有说明进行操作，即

    1. 签名 - Ubuntu：

      wget --no-check-certificate https://download.01.org/gfx/RPM-GPG-KEY-ilg-4 -O - | \ sudo apt-key 添加 -

    2. sudo apt update && sudo apt full-upgrade

    无需再次运行图形安装程序。

    附加信息（题外话）：删除 Ubuntu Tweak PPA，因为它不适用于 16.04。而是为 xenial (deb) 搜索重新打包的 UT 安装程序。
