Linux 版英特尔图形更新工具 - 下载后无法对软件包进行签名（Ubuntu 16.04）

当我运行图形更新工具时，一切运行正常，直到我到达最后阶段，如下所示：

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

错误输出为：

W:The repository 'http://ppa.launchpad.net/upubuntu-com/ppa/ubuntu xenial Release' does not have a Release file., W:Data from such a repository can't be authenticated and is therefore potentially dangerous to use.,

我已遵循https://01.org/linuxgraphics/downloads/intel-graphics-update-tool-linux-os-v2.0.2并按照 Ubuntu 下的解释进行操作。

我甚至做到了sudo apt update && sudo apt full-upgrade

并出现以下错误

Err:13 http://ppa.launchpad.net/upubuntu-com/ppa/ubuntu xenial Release
  404  Not Found
Hit:14 https://download.01.org/gfx/ubuntu/16.04/main xenial InRelease

我该如何解决这个问题，以便我可以使用英特尔软件来更新我的 Ubuntu 上的图形驱动器？

答案1

这个 repo 使用了一个已弃用的摘要算法，SHA1 被发现对于此目的来说太容易发生冲突。

您需要联系存储库的维护者并要求他们使用更好的摘要算法重新生成发布文件。
