在 Sound Juicer 的首选项中，用户可以指定复制 CD 数据的文件类型，但是如何指定所需的比特率，即音频质量？
如何使用 Lubuntu 18.10 将音频 CD 复制到我的 Android 8.1.0 手机？
我必须做什么才能输入日语？
我希望按照Wakisaka 的建议使用 fcitx-mozc，但是当我通过“首选项”>“Fcitx 配置”添加“键盘 - 日语”时，我只得到一个带有罗马字母输出的 qwerty 布局，没有通过输入像“痛”这样的日语单词形成的日语。
当我取消选中“仅显示当前语言”并搜索“Moz”时，没有 Mozc 选项。
在通过开始搜索 > 键盘布局的“键盘和鼠标”中，我有“键盘型号：戴尔 Latitude 笔记本电脑”，因为这台笔记本电脑是戴尔 Latitude D620。我试过添加键盘布局：也有日语，用 Super+Space 切换，但仍然没有日语输出。“假名”变体确实让我可以从每个键输入片假名，但我需要输入 qwerty 或 dvorak 将平假名转换为汉字或片假名。
我想知道我是否找到了提示：An 18.04 user was known to edit /usr/share/ibus/component/mozc.xml，但我的文件夹缺少此文件。
编辑：我现在已经安装了fcitx-mozc.

编辑：我能够让它与本指南一起工作。
（三年前的这个答案似乎有我最终实施的解决方案，如下面的答案所述，尽管我认为 fcitx 已经安装在 Lubuntu 18.10 中。）
默认设置是在任务栏中显示所有打开的应用程序，而不考虑活动桌面。我希望仅在该桌面的任务栏中显示活动桌面中的窗口。如何在任务栏中仅显示活动桌面的应用程序？
我在Quassel 文档中执行了命令，在文件 > 网络 > 配置网络中单击 irc.ubuntu.com:8001 的“编辑...”并选中“使用 SSL”（没有代理，高级选项卡中没有任何内容被更改）。

我在 Settings > Configure Quassel... > IRC > Identities > Advanced > Use SSL Certificate 中找到了加载证书的部分：这不是我们应该指定上面创建的根 CA 的地方吗？但是当我单击“加载”时，我看不到指定 .config 文件夹的方法，该文件夹显然是隐藏的。我该如何进行？

首先，我注意到我启动的 USB 被列出了两次：
为了调查，我打开文件夹查看器并单击查看已安装的驱动器，然后遇到了第二个错误：
然后，检查新的 qlipper 软件，它似乎没有正确显示，点击这个显示的项目什么都不做：
md5sum 与规定的哈希匹配，我在启动 lubuntu 之前检查了磁盘是否有错误，没有发现错误。那么由于各种原因，这一切正常吗，还是我不应该尝试从这个 liveUSB 安装？
如果我单击系统工具 > Fcitx 并单击键盘，我的计算机将冻结，直到我杀死 lxpanel，并且我的 wifi 显示两次，如下图所示。我将在一个单独的问题中询问如何修复 Fcitx，但对于这个问题：如何修复 lxpanel 显示 wifi 两次？
尝试按指示安装，我的终端输出包含以下内容：

问题是我的笔记本电脑是 32 位的，而这个软件是 64 位的吗？我应该将服务器更改为其他国家/地区吗？（我该怎么做？）
我怀疑答案是没有可用的 32 位版本，快照会自动考虑我的处理器类型，因此 32 位通道中没有安装文件。
