我最近从 Windows 迁移到了 Ubuntu。
我的当前语言环境显示以下输出：

有人能帮我解决这个问题吗？由于我对此很陌生，所以如果能详细说明我将不胜感激。
答案1
这里可能存在几个问题，但主要问题可能是我在第三点中提到的区域设置：
qmail1) 您可以先尝试删除似乎导致问题（并阻止您安装任何其他程序）的程序（ ），方法是运行：
sudo apt-get remove qmail
或者如果你想保留它并尝试配置它（和其他任何东西），运行
sudo dpkg --configure -a
dpkg-reconfigure在实际配置该包之前，我们无法使用它。
现在请尝试运行sudo apt-get update。
2) 即使您的错误消息包含有关主机名的信息，但这可能是一个转移注意力的借口，正如您在评论中讨论的那样。不过，您仍然可以检查 的输出cat /etc/hostname和 顶部的主机名/etc/hosts是否相同。
3) 现在，您的主要问题可能与您的语言环境设置有关，即使 的输出locale看起来没有什么特别的问题。但是，您的问题产生的确切错误在 Ubuntuforums 上已经发生过几次。一般建议是运行locale-gen它并提供你的特定设置；例如，在你的情况下你可以运行：
sudo locale-gen en.IN
您可能还需要添加en_IN.ISO8859-1或en_IN.UTF-8，具体取决于您希望如何指定编码设置。文章在这里非常有用，如果需要，可以进一步修改以满足您的需求。运行后locale-gen，还可以运行
sudo dpkg-reconfigure locales
如果这不能解决问题，请参阅有关语言环境的更多文档Ubuntu 维基。然而，解决方案应该与语言环境有关，因为这似乎是一个常见问题。
答案2
编辑 /etc/hosts 文件以更改
127.0.0.1 localhost
127.0.1.1 desktop
到
127.0.0.1 localhost
127.0.1.1 desktop.your.domain desktop
例如：使用我的机器
127.0.0.1 localhost
127.0.1.1 vnpt
到
127.0.0.1 localhost
127.0.1.1 vnpt.vnpt-domain vnpt
之后您就可以安装 qmail。
