直到最近我一直在使用ppa:nginx/development，但突然我无法在 14.04 上从那里安装 nginx 版本。
https://launchpad.net/~nginx/+archive/ubuntu/development还指出：
PPA 不再支持以下 Ubuntu 版本，因为构建依赖关系或由于版本年龄而无法解决的问题：
- 值得信赖 (14.04)
在 14.04 上获得更新版本的 nginx 时，我还有哪些其他选择？
我至少需要http2支持（我在某些机器上成功运行了 1.9 和 1.13）。
根据更新日志，前几天推送了一个安全更新：
主管（3.0b2-1ubuntu0.1）可信赖的安全性；紧急=中等
- 安全更新：通过 XML-RPC 进行任意代码注入
- debian/patches/CVE-2017-11610.patch：在 supervisor/test/test_xmlrc.py、supervisor/xmlrcp.py 中禁用 XML-RPC 调度中的对象遍历。
- CVE-2017-11610

这是我安装的包：
$ dpkg -p supervisorO
Package: supervisor

Description: A system for controlling process state
Supervisor is a system for controlling and maintaining process state,
similar to what init does, but not intended as an init replacement.
.
It will manage individual processes or groups of processes that
need to be started and stopped in order, and it is possible to
control individual process state via an rpc mechanism, thus allowing
ordinary users to restart processes.

这就是我更新的方式以及过程的进行方式：

手动启动虽然有效：sudo service supervisor start
我在以下位置找到了这个dpkg.log：

我做了一个人为的空间间隙，在那里我停下来看看情况，然后手动启动它。
我做错什么了吗？我通常只是执行sudo apt-get upgrade，但是我已经从同事那里听说过这个问题，但她没有记录细节，所以我使用了测试机器来执行此操作。
谢谢！
在暴发户之前，很容易获得适当的自动完成功能，例如我输入sudo /etc/init.d/rsys<tab>和我想做什么，然后我就走了。
现在我需要 (?) 来写sudo stop rsys<tab>，但它不起作用；似乎 bash 不知道此时可以启动/停止哪些服务。
是否有 Ubuntu 软件包或手动激活？
我已经习惯了这种 Windows 行为，使用CTRL+SHIFT+Cursor Keys我可以逐字选择文本。CTRL+Cursor Keys逐字跳跃，我经常将其与SHIFT选择文本结合使用。
这似乎是“Windows 事物”，因为它只适用于所有应用程序。现在转向 Ubuntu 10.04，它不起作用。CTRL+SHIFT+Cursor Keys只是表现得像CTRL+Cursor Keys，即我在单词之间跳转，但我不能那样选择它们。
另一个陷阱：我习惯CTRL+Cursor Keys在单词之间快速移动，按下SHIFT，释放CTRL并移动Cursor Keys以逐个字符选择文本，它也不起作用。我需要完成两个键的释放。
有没有办法启用它？
