尽管 yum 似乎能够成功访问代理，但我还是不断收到 yum 代理连接失败错误 407。
我有以下运行 yum 的日志，其中包含最高的调试和错误执行list packages命令：
# yum -d 10 -e 10 --rpmverbosity debug --enablerepo=\* list packages

忽略此错误可以吗？yum 的功能是否受到了影响？如果是，我该如何修复？
我已经通过环境变量（http_proxy、ftp_proxy 等）以及通过以下方式正确配置了代理/etc/yum.conf
我知道代理配置是正确的，因为 yum 能够像上面一样列出软件包。甚至还有一个进度条反映下载情况。
答案1
尝试删除代理/yum.conf 代理条目等的环境变量，并在 /etc/rhsm/rhsm.conf 中输入代理详细信息。
