正如您在屏幕截图中看到的那样，我被告知apt-get install oracle-java8-install但它给了我一个错误，我没有遇到 java-common 的依赖项。好，太棒了。现在我尝试安装apt-get install java-common。又一个错误！现在我完全迷路了。

Ubuntu 是 18.04 版本，这么多年了，为什么安装这么简单的东西还是这么 PITA。

我要哭了。

在此处输入图像描述

我正在尝试在我的 ubuntu 12.04 上安装letsencrypt，但我收到了这些 404 错误，我不太确定如何解决它们。

我不明白为什么这种情况总是发生在我身上。我不久前安装了一些东西，它工作正常，但加班这些东西由于某种原因消失了。有人可以向我解释为什么会发生这种情况，当有人发布应用程序时，他们为什么不将所有必要的文件包含在正在安装的包中，而不是当场下载？

我一直在寻找如何使用 Ubuntu 12.04 将 IP 地址（例如 123.123.321.1）列入白名单。但是每个人似乎都给出了很长的详细答案。是否只有 1 个简单的命令可以将 IP 地址列入白名单？我想将一个 IP 地址列入白名单，以便它可以通过 SSH 端口 22 进行连接。这个解决方案也可以与 centos 等其他 linux 风格一起使用吗？

我目前使用的是 ubuntu 12.04，因为这是旧版本的 ubuntu，所以我安装了 git 1.7.9.5，但我不确定如何将其升级到 git 2.x。

  • 我应该输入什么来安装 git 2.x (sudo apt-get install git)？
  • 安装 git 2.x 时，它会覆盖 git 1.7 吗？如果不是，您如何选择使用哪一个？
  • 我如何找出我的系统上安装了 git 1.7 的位置？

我似乎无法找到一个快速命令来查看服务器上所有被禁止的 IP。或者是否有我可以编辑的文件？

我猜 fail2ban 是输入所有要禁止的 IP 的那个。我在哪里调整它的设置？

我似乎只能在禁用 ufw 时才能远程登录到我的服务器。我似乎无法找到如何解除自己的禁令。我什至不知道为什么我首先被禁止。是否有某种日志可以查看所做的所有尝试？
