我意识到了安全隐患，也理解了为什么 apt-key 被弃用。但就我的使用情况而言，我并不关心。

我想要运行：

$ apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv-keys CC116F55AA7F2382

没有任何警告。但我看到：

apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv-keys CC116F55AA7F2382 
Warning: apt-key is deprecated. Manage keyring files in trusted.gpg.d instead (see apt-key(8)).
Executing: /tmp/apt-key-gpghome.KVaQ390iTM/gpg.1.sh --keyserver hkp://keyserver.ubuntu.com:80 --recv-keys CC116F55AA7F2382 /dev/null

如何强制不输出 stdout 和警告？我只想看到实际发生的错误的输出。（我知道该脚本在已经知道密钥的系统上运行，因为我之前已经运行过它。）

我试过：

  • apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv-keys CC116F55AA7F2382 > /dev/null
  • apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv-keys CC116F55AA7F2382 2>&1 > /dev/null
  • apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv-keys CC116F55AA7F2382 2>&1 /dev/null

在运行期间apt-get dist-upgrade，我在设置软件包时不小心通过 Ctrl + C 取消了它。

我现在想知道我的系统上是否有任何处于损坏状态的东西。我尝试运行：

sudo dpkg --configure -a

然而没有任何报道。

如果我运行：

sudo apt-get dist-upgrade

注意到变化。我想知道：我的系统有什么问题吗？我怎么知道？如果有东西坏了，我将如何修复它？

我知道有一个类似于 的运算符*，不同之处在于它适用于所有子目录。

假设您有一个文件夹结构：

.
├── bar
│   ├── foo
│   │   └── baz
│   │       └── hurz
│   │           └── lolz
│   │               └── hello.txt
│   └── poit.txt
└── fnord.txt

然后ls用单星*列出：

$ ls *.txt
fnord.txt

我希望双星运算符**可以处理子文件夹，但它并不完整。我知道这可以工作，因为我在另一台机器上启用了它，但我忘记了如何。

$ ls **/*.txt
bar/poit.txt

我期待输出看起来像：

ls **/*.txt
bar/foo/baz/hurz/lolz/hello.txt  bar/poit.txt  fnord.txt

如何**调用操作员以及如何正确激活它？

我安装了一个全新的 Ubuntu 17.10 (GNOME)。

它的 GNOME Shell 似乎已被修改为与 Unity shell 类似，因此在左侧面板上我总是看到一个面板（又名 Ubuntu Dock）提供图标来启动不同的应用程序。

启用侧边栏的 gnome shell 桌面屏幕截图始终显示在左侧

我发现在全屏窗口中运行的程序特别烦人。

如何使侧边栏在正常模式下始终消失？

我不介意在默认情况下通过超级键访问的“活动概览”中看到它，但我不想看到我何时在桌面或其他应用程序中。

我想保留标题栏。

最后，如果有人在 Ubuntu 16.04 上切换到 GNOME shell，我正在寻找提供的类似体验。

正如这里指出的那样，我正在改变我在一堆机器上安装 docker 的方式。它在一个上运行良好，但是这个行为很奇怪。

我已经导入了密钥：

我在我的谷歌浏览器中打开了一些在线教程。它告诉我在终端中运行一些命令。

我目前的工作流程是通过鼠标选择必要的部分，然后通过在终端中单击鼠标中键插入复制的文本。

我想避免在大多数情况下使用鼠标，所以我想只使用键盘来突出显示网页上的文本。我希望将文本自动保存到类似于鼠标选择的缓冲区中，但即使这样也可以在不使用鼠标选择文本的情况下按 ctr+c 就可以了。

Chrome 中是否有用于该目的的模式？

我在 Dell E5450 上新安装了 Ubuntu 14.04。硬盘在安装时已完全加密。

笔记本电脑的键盘工作正常，但在尝试外接 USB 键盘和鼠标时遇到问题。他们只是不会通过 grub 菜单工作。

（我什至觉得 USB 在 grub 后根本无法工作。）

这不是硬件问题，因为 Live Stick 可以在键盘和鼠标支持下启动。

然而，一旦我必须输入密码来解锁加密的硬盘，我就无法输入，甚至在 Ubuntu 本身也无法识别。

我调查了这个问题并发现了错误报告，但所提供的解决方法似乎都不适合我。

我尝试将这些添加到我的模块列表中：

$ cat /etc/initramfs-tools/modules
# List of modules that you want to include in your initramfs.
# They will be loaded at boot time in the order below.
#
# Syntax:  module_name [args ...]
#
# You must run update-initramfs(8) to effect this change.
#
# Examples:
#
# raid1
# sd_mod

hid
usbhid
hid_generic
ohci_pci

和运行

sudo update-initramfs -u

然而没有运气。

如何使用全盘加密为 Ubuntu14.04 修复我的 USB？

对于我的 Gnome Shell，我已禁用工作区应仅在主显示器上。所以现在，每当我切换工作区时，两​​个显示器都会按应有的方式切换它们的内容。

然而，当我按下Meta以预览我的工作区时，我所看到的只是主显示器工作区内容的预览。

这使得在我的工作空间中导航变得非常困难，因为我必须知道某个窗口隐藏在哪个辅助监视器上。

如何在预览中预览所有显示器的内容？
