那些遇到过的问题

无法在 Kubuntu 19.04 中将语言改回英语

San*_*shi 7 kde language kubuntu kde5

问题：

在“设置”->“区域设置”中，我添加了马拉地语和印地语语言以查看其工作原理和翻译内容（我知道马拉地语和印地语）。重新启动后，语言更改为马拉地语。现在，我想恢复到英语，因为这是我在处理计算机时习惯的语言。但是，当我单击“添加语言...”按钮时，没有任何反应，也没有出现对话框。因此，除了作为添加语言存在的语言之外，我无法将语言更改为任何其他语言。

重现步骤：

转到设置 -> 区域设置 -> 单击添加语言... -> 添加印地语 - ????? （或马拉地语 - ?????，其他人可能不会给出相同的结果，不知道） -> 单击应用 -> 重新启动计算机 -> 转到 ????? ??????? （??????? ????????? 在马拉地语的情况下）-> 区域设置-> 单击添加语言...

我尝试过的：

  1. LANGUAGE 环境变量在哪里设置？
  2. 语言环境：重置丢失的设置
  3. /sf/ask/1917103961/
  4. https://websiteforstudents.com/how-to-change-to-your-native-language-on-ubuntu-17-10/
  5. https://www.shellhacks.com/linux-define-locale-language-settings/
  6. 部分菜单有中文/日文！

附加信息：

系统设置有时会崩溃。

任何帮助表示高度赞赏！

根本原因：

当我们通过“系统设置”>“区域设置”添加语言时，它会添加为 KDE Plasma 的（桌面环境）语言，而不是系统语言。因此，虽然系统语言显示英语（运行locale在终端中运行），但我们仍然会看到桌面采用区域设置中指定的语言。

这也是为什么使用

  1. sudo locale-gen en_US.UTF-8或者
  2. sudo localectl set-locale LANG=en_US.utf8或者
  3. 投入export LANG=en_US.utf8并~/.bashrc运行source ~/.bashrc

不会影响区域设置中设置的语言设置。

解决方案：

转到~/.config/plasma-locale-settings.sh，打开它并确保它包含以下内容： 

# Generated script, do not edit
# Exports language-format specific env vars from startkde.
# This script has been generated from kcmshell5 formats.
# It will automatically be overwritten from there.
# I am from India, hence en_IN, shouldn't matter much
export LANG=en_IN
export LANGUAGE=en_US

然后，转到~/.config/plasma-localerc，打开它并确保它包含以下内容： 

[Formats]
LANG=en_IN

[Translations]
LANGUAGE=en_US

关闭计算机并重新启动。你应该回到英语上来。如果没有，请通过评论告诉我:)
