在我的 Raspberry Pi 上执行“sudo apt-get dist-upgrade”期间，在等待用户输入时，我的 ssh 连接被重置。我不是在屏幕上跑步。最后几行看起来像这样：

Installing new version of config file /etc/init.d/procps ...

Configuration file '/etc/sysctl.conf'

我需要在我的 Ubuntu 14.04 机器上安装 Clang 4.0 和 Clang++ 4.0。我在 apt-get 软件包列表中可以找到的最新版本是 3.5。如何安装 4.0？

好的，我有一个在 Ubuntu 机器上管理的网站，但我已经有一段时间没有更新 apache2 了。我想了解最新的安全补丁等。

问题是我没有测试或质量保证服务器或任何可以“实验”的东西，我不想破坏我的网站。

在相当活跃的网站上进行 apt-get 更新/升级到 apache2 有哪些风险？

如果我运行命令apt-get install [package_name]并点击CTRL-C中间过程，它会停止安装并回滚到原始状态吗？

我有一台在 Ubuntu 12.10 上运行的虚拟机。当我尝试跑步时

apt-get install imagemagick

我收到几个 404 错误：

我一直在阅读有关为什么通常不会在apt-get网络活动中部署加密的信息。并了解到它会检查来自 repo 的数据的签名，对吗？

但是现在，这种检查是如何发生的？如何做到真正安全？例如，如果文件和密钥在服务器中并以未加密的方式发送，那将如何工作？有人可以修改两者......

我尝试将 Ubuntu 从 14 升级到 15，在此过程中我遇到了一些问题。升级说它成功完成，但过程中有错误。然后我重新启动了我的电脑，它不会启动。所以我得到了一张 Live CD 并按照这里的步骤操作：

https://help.ubuntu.com/community/LiveCdRecovery#Update_Failure

在第 9 步

apt-get upgrade

我收到以下消息：

我尝试了一切，但没有任何进展。聪明的灵魂能帮上忙吗？

当然只是sudo apt-get -f install不起作用，同样的错误。

You might want to run 'apt-get -f install' to correct these:
