无法提取 amdgpu tar.xz

Question

我正在运行 Ubuntu 17.10，但无法提取某个 tar 文件。尝试提取文件时，我收到以下消息：

There was an error while extracting”amdgpu-pro-17.40-492261.tar.xz”
“Not an archive”

任何帮助，将不胜感激。

Answer 1

该特定文件有点受屏蔽，我怀疑您只下载了 302 错误页面。但是，以下一个衬垫在我的系统上运行良好：

wget --referer http://support.amd.com \
https://www2.ati.com/drivers/linux/ubuntu/amdgpu-pro-17.40-492261.tar.xz

注意--referer选项的使用。看起来已经做出了一些努力来防止人们使用来自AMD 站点外部的链接。这很容易，我相信也很合理，以这种方式规避。

从 wget 手册页：

--referer=url
   Include `Referer: url' header in HTTP request.  Useful for retrieving
   documents with server-side processing that assume they are always being
   retrieved by interactive web browsers and only come out properly when
   Referer is set to one of the pages that point to them.

我自己系统上的完整过程如下：

1. 初始下载：

andrew@illium~$ wget --referer http://support.amd.com \
