我正在尝试在我的 ubuntu 12.04 上安装 letsencrypt，但是我收到了这些 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。我之前安装了一些东西，它运行良好，但随着时间的推移，这些东西不知为何消失了。有人能向我解释为什么会发生这种情况吗？当有人发布应用程序时，为什么不直接将所有必要的文件包含在要安装的软件包中，而是当场下载？

答案1
您的 ppa 存储库有问题。这种情况有时会随着时间的推移而发生。这通常意味着软件作者不再支持他们的软件（libssl1.0.2、openssl、libssl-dev），并删除了他们那边的文件。
在terminal...
cd /etc/apt # change directory
grep ondrej sources.list # search for ondrej
如果这个 grep 返回答案，那么......
sudo gksudo gedit /etc/apt/sources.list # edit the file
#并在有问题的行前面放置一个。保存文件并退出 gedit。
接下来我们将在所有 *.list 文件中搜索...
cd /etc/apt/sources.list.d # change directory
grep ondrej *.list # search for a {filename}.list
您可能只会得到一个文件名作为 grep 命令的输出。记下文件名。接下来我们将删除该文件...
sudo rm -i /etc/apt/sources.list.d/enter_filename_here.list
