我正在做一个 NLP 研究项目。为此，我必须分析一个大约 10mb的 unicode (Sinhala)文本文件，它会在 Google 文档中打开。但是当我尝试从 gedit 打开它时，我收到了这个错误

意外错误：转换输入中的字节序列无效

因此，我遵循了这个类似的问题并尝试了第二个答案，该答案建议在终端中运行此命令：

gsettings set org.gnome.gedit.preferences.encodings auto-detected "['UTF-8', 'CURRENT', 'ISO-8859-15', 'UTF-16']"

我在终端得到了这个结果：

GLib-GIO-Message: Using the 'memory' GSettings backend.  Your settings will not be saved or shared with other applications.
No such key “auto-detected”

所以，没有成功。当我尝试在 gedit 中打开文件时，我遇到了同样的错误。我怎样才能解决这个问题？如何在gedit中打开此文件？

我安装了 Visual Studio，但它没有显示应用程序的图标。所以我按照这个来设置一个图标。

当我进入时，/usr/share/applications我看到了Visual Studio Code.desktop的文件。但由于我没有访问权限，我无法对其进行编辑。所以我打开终端并尝试用. 因此，首先我尝试使用 . 检查名称。但它没有列出图标。 sudo geditls/usr/share/applications 中的 Visual Studio 代码 在此处输入图像描述

这是为什么？如何编辑.desktopvscode 来设置图标？

我使用以下命令在我的 Ubuntu 17.10 上安装了便签

sudo add-apt-repository ppa:umang/indicator-stickynotes
sudo apt-get update
sudo apt-get install indicator-stickynotes

在我安装它之后，它显示为一个应用程序。但它没有打开。当我点击它时，什么也没有发生。

这是为什么？如何在我的 PC 上运行便签？

一段时间以来，我一直在使用 Ubuntu 16.04 和 Windows 10 作为双启动。每天我都将 Ubuntu 用于开发目的，将 Windows 用于其他一些东西。有时我Error mounting device在尝试进入分区时在 Ubuntu 上遇到错误。发生这种情况时，我运行sudo ntfsfix dev/sdaxx命令并修复它。

现在，当我尝试从 Ubuntu 迁移到 Windows 时，出现蓝屏提示 UNMOUNTABLE_BOOT_VOLUME并且我无法进入 Windows。有什么办法可以在 Ubuntu 中修复该错误？因为它说要修复我必须从 Windows 可启动驱动器 (USB) 进入 Windows。还有其他方法吗？

PS：在 Windows 中出现错误后，当我登录 Ubuntu 时，相同的 C 分区会抛出Error mounting device. 其他分区工作正常。ntfsfix在C 分区上运行后，我也可以访问它。

我做错了什么？我只需要进入 Windows。

这是我得到的错误。

今天早上，我在 Windows 10 旁边安装了 ubuntu 16.04 作为双启动。安装第一次 grub 菜单后顺利进行。从下一次我的笔记本电脑直接启动到 Windows 10。要进入 grub，我每次打开时都必须按 F9。所以我通过在ubuntu上安装bootlaoder修复来修复它。现在我在 grub 上有很多条目，而且一团糟。那么，我该如何清理呢？任何帮助，将不胜感激 。谢谢

这是我得到的 grub 菜单

我在 Ubuntu 15.04 上使用 MySQL 没有任何错误。但昨天我从昨天的 15.04 升级到 16.04LTS（15.04 到 15.10 和 15.10 到 16.04LTS）。我现在有一些问题

当我使用检查 MySQL 状态时

mysqladmin -u root -p status

我收到此错误

 mysqladmin: Can't read dir of '/etc/mysql/conf.d/' (Errcode: 2 - No such file or directory)
 mysqladmin: [ERROR] Fatal error in defaults handling. Program aborted!

所以我尝试使用删除它

sudo apt-get remove --purge mysql-server mysql-client mysql-common

我收到了这个错误
