Ubuntu 18.10 宇宙生命终结

从昨天开始，apt install 命令不再起作用，我尝试升级我的系统版本，但我得到了与 apt-get update 命令相同的错误

  1. 存储库仍然可以在http://old-releases.ubuntu.com/ubuntu上找到。您可以在 /etc/apt/sources.list 中更改它们，将所有出现的http://archive.ubuntu.com替换为http://old-releases.ubuntu.com。

    之后， apt-get upgrade 将再次起作用。

    最后我强制降级更改source.list ...我关注了这篇文章：https ://linuxconfig.org/how-to-downgrade-ubuntu-linux-system-to-its-previous-version

    1. 这是因为您的 Ubuntu 版本已过时。这意味着 Ubuntu 不提供安全支持，因为系统太旧了。您需要禁用源列表中的错误存储库，然后apt再次运行。

    2. apt-update不会升级您的系统。它仅更新系统中的存储库。如果您需要升级到另一个 Ubuntu 版本，请运行do-release-upgrade. 否则，运行apt-upgrade -y升级系统包。显然，sudo如果您不是root用户，请运行。

  4. 您可以使用 Ubuntu 18.04，因为它与您所拥有的很接近，是一个长期服务版本，并且更新得很好。我定期更新我的 Ubuntu 机器。
