Curl on Debian 10返回错误html而不是pdf

Question

我正在从议会下载大量pdf。我抓取了pdf地址，现在尝试下载它们。

为此，我在一个大学云上建立了一个debian实例。

这对他们中的大多数人来说都很好，但对4个议会来说，我下载了一个必须接受cookie的错误页面。结果是一个以pdf文件结尾的html页面，主要包含我是否接受cookie的问题。

这个错误不会发生在Ubuntu或Windows 10上。

这是debian上旋度的输出：

curl -Iv4 http://dokumentation.landtag-mv.de/parldok/dokument/44970/eu_ratspraesidentschaft.pdf

与Ubuntu相比，在那里我可以获得pdf

$ curl -Iv4 http://dokumentation.landtag-mv.de/parldok/dokument/44970/eu_ratspraesidentschaft.pdf
