我在代理内使用 Linux Mint。我已经在中配置了代理设置/etc/environment我已经为整个系统https://askubuntu.com/questions/257290/configure-proxy-for-apt）来配置 apt 代理。
但是，当我尝试打电话时 sudo apt-get update，我得到以下结果：
Ign:1 http://archive.canonical.com/ubuntu bionic InRelease
Err:2 http://archive.canonical.com/ubuntu bionic Release
Redirection loop encountered

我在互联网上进行了一些搜索，但没有找到该问题的解决方案。另外，我记得当我必须使用该curl命令时，我必须设置代理并启用 cookie，否则我会得到这些“重定向循环”。
请问，我应该怎么做才能解决这个问题？
谢谢。
