我尝试使用 fedup 将 Fedora 18 更新到 19，但 curl 出现错误“请求的 URL 返回错误：403 禁止访问”
我位于防火墙和 http_proxy 环境变量后面。它在其他应用程序中有效。
root@localhost ~]# fedup-cli --network 19 设置存储库... 以下存储库没有可用的升级：sublime2 获取启动映像... .treeinfo | 1.1 kB 00:00
下载失败：无法获取启动映像：curl#22 - “请求的 URL 返回错误：403 禁止访问”
我运行了 curl 并且它有效：
curl -v -o index.html --proxy-any www.bbc.co.uk

我想知道我是否应该自己构建 fedup？
我最终从 ISO 文件进行了更新：
fedup-cli --iso Fedora-19-x86_64-DVD.iso

答案1
Yum 不支持http_proxy环境变量。您需要在配置文件中设置proxy(和proxy_username/ proxy_password) /etc/yum.conf。
