好的，所以这是从 16.04.1 LTS 升级到 18.04.1 LTS，服务器是无头的。升级完成并重新启动完成后，会发生以下情况：

尝试升级软件包只会导致以下结果：

它正在谈论的是Dbus吗？无论如何，恢复怎么样？

什么？dns坏了吗？

~$ wget www.google.com
--2018-11-10 01:55:16--  http://www.google.com/
Resolving www.google.com (www.google.com)... failed: Temporary failure in name resolution.
wget: unable to resolve host address ‘www.google.com’

看起来像。嗯，ifconfig 不显示 dns。谷歌引导我回答这个问题，让我们试试。

~$ systemd-resolve --status
sd_bus_open_system: No such file or directory

好吧，我现在越来越迷茫了。谷歌现在发现这个问题，是关于docker的，这不是我的情况，但也提到了systemd isnt pid 1的问题：

~$ ps aux

我猜？这是根本问题，还是症状？我怎样才能解决这个问题？

min protocol = SMB2由于某些原因，我最近在我的文件服务器（samba 4.3.9）上禁用了 SMB1（添加到 smb.conf）。

Windows 客户端仍然可以访问文件共享，但我在 ubuntu 客户端上也有一些挂载的网络文件夹，它们目前失败了。客户端当前正在使用 cifs 将共享挂载到 fstab 中的文件夹上。

我应该怎么做才能解决这个问题？在 Ubuntu Server 16.04.1 上永久挂载网络共享的最佳实践是什么？

现在，我的目标是将整个 xubuntu 安装的键盘布局更改为我自己的修改版本。我认为做到这一点的方法是制作一个 X11 键盘映射并加载它 - 但一如既往有一千种方法可以做事，我愿意接受建议。

我创建了一个修改过的 xkb 符号键盘映射，我想在我的 xubuntu 安装中使用它，但我在设置对话框的布局列表中看不到它。

我将以下内容放入/usr/share/X11/xkb/symbols/se

partial alphanumeric_keys
xkb_symbols "psvorak" {
name[Group1]="Sweden - PSvorak";
include "keypad(comma)"
include "level3(ralt_switch)"

key <AD01>  { [odiaeresis, Odiaeresis, dollar, none ]   };
<etc>
};

没有效果。

我还尝试根据http://www.linuxquestions.org/questions/linux-desktop-74/problem-creating-custom-xkb-layout-605568/重新生成symbols.dir，而 xkbcomp 说我没有错误文件，没有其他变化。它在 gui 中不可用，并且 setxkbmap（其语法非常混乱）仅响应“找不到文件”或“加载新键盘描述时出错”。

我确实设法创建了一个控制台键映射并使用 loadkeys 加载它......

charset "iso-8859-1"
keymaps 0-2,4-6,8,12
alt_is_meta
strings as usual
keycode   1 = Escape
    alt     keycode   1 = Meta_Escape
keycode   2 = one              exclam
    alt     keycode   2 = Meta_one
keycode   3 = two              quotedbl         at
    control keycode   3 = nul
    alt     keycode   3 = Meta_two
<etc>

...但它似乎只在Ctrl- Alt-F1控制台中工作。
