wget 在可访问文件上给出 403

Question

我第一次遇到奇怪的问题。我通常通过 conda 安装软件，但时不时地我无法使用 conda install 因为 conda 试图访问一些配置文件时出现 403。尝试使用 wget --spider --debug https://conda.anaconda.org/anaconda/noarch/current_repodata.json 下载这些文件时，出现相同的 403 错误。

DEBUG output created by Wget 1.19.4 on linux-gnu.

这些文件可以通过浏览器访问，并且一直可以使用 wget 和 conda 访问，直到昨天，当我安装一些与这些网络访问无关的工具时。 wget怎么会下载失败呢？

Answer 1

所以通过重新安装 apt-get 解决了这个问题。那里的某些配置文件一定是搞砸了。

wget 在可访问文件上给出 403

wget gives 403 on accessible files

anaconda

conda

wget
