我最近安装了一台 Ubuntu 服务器 22.04。它运行了几天，我调整了前几个旋钮，直到有一天，我无法再连接到互联网。它在登录服务器并尝试更新/升级时启动。
我盯着 0％[工作] 静静地看了一会儿，然后：
Ign:1 http://nova.clouds.archive.ubuntu.com/ubuntu jammy InRelease
Ign:2 http://security.ubuntu.com/ubuntu jammy-security InRelease
Ign:3 http://nova.clouds.archive.ubuntu.com/ubuntu jammy-updates InRelease
Ign:2 http://security.ubuntu.com/ubuntu jammy-security InRelease
and finally a bunch of errors.
