How to Uninstall Deb Packages in Ubuntu
|
||||
======
|
||||
Installing applications from a deb file is quite simple. You double click on it and it opens in the Software Center application and you install it from there.
|
||||
|
||||
[Installing applications from a deb file][1] is quite simple. You double click on it and it opens in the Software Center application and you install it from there.
|
||||
|
||||
But what about uninstalling a .deb package in Ubuntu or Debian? How do you remove the package you installed some time back.
|
||||
|
||||
While there are several ifs and buts around it, the simplest and most reliable way of deleting a deb file is by using the apt remove command.
|
||||
|
||||
```
|
||||
sudo apt remove program_name
|
||||
```
|
||||
|
||||
As you can see, **you need to know the exact package name here**. This may not always be straightforward. For example, if you install Google Chrome on Ubuntu, the program is known as ‘google-chrome-stable’ in the command line. Did you already know that? I guess not.
|
||||
|
||||
In this tutorial, I’ll go into detail about finding the exact package name and then using it to remove the application. I’ll also discuss using a graphical method for deleting .deb packages.
|
||||
|
||||
### Removing package installed via deb files from Ubuntu
|
||||
|
||||
Before I show you how to remove deb packages from the command line, let’s just quickly look at it in the Software Center application.
|
||||
|
||||
#### Method 1: Check if the application can be removed from the software center
|
||||
|
||||
Ubuntu has the Software Center GUI application that allows to search for applications, install them and remove them.
|
||||
|
||||
The Software Center may not show the application installed when you search for it.
|
||||
|
||||
![Searching for installed applications may not show any results in Ubuntu Software Center][2]
|
||||
|
||||
However, you may still find it under the “Installed” section if you scroll down. The external applications are usually displayed without their logo.
|
||||
|
||||
![Some installed applications can be found in the ‘installed’ tab of the Software Center][3]
|
||||
|
||||
If you find it, you can remove the application by clicking the trash icon or remove button.
|
||||
|
||||
![Removing applications from the Ubuntu software center][4]
|
||||
|
||||
**Bottom line: Check if the application can be removed from the software center.**
|
||||
|
||||
#### Method 2: Delete applications using apt command
|
||||
|
||||
I am presuming that you don’t know the exact name of the application command. It is only natural that you may not know that Google Chrome is installed as google-chrome-stable and Edge is installed as microsoft-edge-stable.
|
||||
|
||||
The tab completion may help if you have the first few letters. Otherwise, you can [list the installed applications with apt command][5] and use grep to search for the application name:
|
||||
|
||||
```
|
||||
apt list --installed | grep -i possible_package_name
|
||||
```
|
||||
|
||||
For example, you can intelligently guess that the Google Chrome package should have chrome in its name. You may search it like this:
|
||||
|
||||
```
|
||||
apt list --installed | grep -i chrome
|
||||
```
|
||||
|
||||
You may get more than one result in some cases.
|
||||
|
||||
![check if google chrome installed in ubuntu][6]
|
||||
|
||||
If you are not sure what the packages do, you can always get their details with:
|
||||
|
||||
```
|
||||
apt info exact_package_name
|
||||
```
|
||||
|
||||
Once you have the exact package name, you can delete it using the apt remove command.
|
||||
|
||||
```
|
||||
sudo apt remove exact_package_name
|
||||
```
|
||||
|
||||
You can also use apt-get remove or dpkg uninstall commands.
|
||||
|
||||
![Removing applications installed via deb files using the apt command][7]
|
||||
|
||||
#### Method 3: Use Synaptic Package Manager to remove deb applications
|
||||
|
||||
Another method is to use the [Synaptic Package Manager][8]. Before GNOME created its graphical package manager in the form of the Software Center, Synaptic was the default GUI package manager in Ubuntu and many other distributions.
|
||||
|
||||
It is still the recommended tool on the [Xfce desktop environment][9].
|
||||
|
||||
Install it first:
|
||||
|
||||
```
|
||||
sudo apt install synaptic
|
||||
```
|
||||
|
||||
Open Synaptic and search for the package name. Look for the installed packages that are marked green. Right-click on them and click on ‘mark for removal’. Hit apply after that.
|
||||
|
||||

|
||||
|
||||
### Did it help you?
|
||||
|
||||
I am more than comfortable using the apt command to remove the packages installed from .deb files. But I can understand that not everyone is comfortable using the command line.
|
||||
|
||||
I find the Software Center lacking when it comes to the removal of applications installed from external deb files. It could do a better job here.
|
||||
|
||||
I hope you have a better understanding of removing deb packages now. Let me know if you have any questions.

如何在 Ubuntu 中卸载 Deb 包
|
||||
======
|
||||
[从 deb 文件安装应用][1]非常简单。双击它，它会在软件中心中打开，然后从那里安装它。
|
||||
|
||||
但是如何在 Ubuntu 或 Debian 中卸载 .deb 包呢？你如何删除一段时间前安装的软件包。
|
||||
|
||||
虽然这有几个如果和但是，但删除 deb 文件的最简单和最可靠的方法是使用 apt remove 命令。
|
||||
|
||||
```
|
||||
sudo apt remove program_name
|
||||
```
|
||||
|
||||
如你所见，**你需要在这里知道确切的包名称**。这可能并不总是直截了当的。例如，如果你在 Ubuntu 上安装 Google Chrome，则该程序在命令行中称为 “google-chrome-stable”。你已经知道了吗？我猜不是。
|
||||
|
||||
在本教程中，我将详细介绍如何找到确切的包名称，然后使用它来删除应用。我还将讨论使用图形方法删除 .deb 包。
|
||||
|
||||
### 从 Ubuntu 中删除通过 deb 文件安装的软件包
|
||||
|
||||
在我向你展示如何从命令行删除 deb 包之前，让我们在软件中心应用中快速查看它。
|
||||
|
||||
#### 方法 1：检查应用是否可以从软件中心移除
|
||||
|
||||
Ubuntu 有软件中心 GUI 应用，允许搜索、安装和删除应用。
|
||||
|
||||
搜索时，软件中心可能不会显示已安装的应用。
|
||||
|
||||
![Searching for installed applications may not show any results in Ubuntu Software Center][2]
|
||||
|
||||
但是，如果向下滚动，你仍可能在“已安装”部分下找到它。外部应用通常不带 logo 显示。
|
||||
|
||||
![Some installed applications can be found in the ‘installed’ tab of the Software Center][3]
|
||||
|
||||
如果找到它，你可以通过单击垃圾桶图标或删除按钮来删除该应用。
|
||||
|
||||
![Removing applications from the Ubuntu software center][4]
|
||||
|
||||
**一句话：检查是否可以从软件中心删除应用。**
|
||||
|
||||
#### 方法 2：使用 apt 命令删除应用
|
||||
|
||||
我假设你不知道应用命令的确切名称。你可能不知道 Google Chrome 安装为 google-chrome-stable 而 Edge 安装为 microsoft-edge-stable，这是很自然的。
|
||||
|
||||
如果你有前几个字母，那么 tab 补全可能会有所帮助。否则，你可以[使用 apt 命令列出已安装的应用][5] 并使用 grep 搜索应用程序名称：
|
||||
|
||||
```
|
||||
apt list --installed | grep -i possible_package_name
|
||||
```
|
||||
|
||||
例如，你可以智能地猜测 Google Chrome 包的名称中应该包含 chrome。你可以这样搜索：
|
||||
|
||||
```
|
||||
apt list --installed | grep -i chrome
|
||||
```
|
||||
|
||||
在某些情况下，你可能会得到多个结果。
|
||||
|
||||
![check if google chrome installed in ubuntu][6]
|
||||
|
||||
如果你不确定这些软件包的作用，你可以随时通过以下方式获取它们的详细信息：
|
||||
|
||||
```
|
||||
apt info exact_package_name
|
||||
```
|
||||
|
||||
获得确切的软件包名称后，你可以使用 apt remove 命令将其删除。
|
||||
|
||||
```
|
||||
sudo apt remove exact_package_name
|
||||
```
|
||||
|
||||
你还可以使用 apt-get remove 或 dpkg uninstall 命令。
|
||||
|
||||

|
||||
|
||||
#### 方法 3：使用 Synaptic 包管理器删除 deb 应用
|
||||
|
||||
另一种方法是使用 [Synaptic 包管理器][8]。在 GNOME 以软件中心的形式创建其图形包管理器之前，Synaptic 是 Ubuntu 和许多其他发行版中的默认 GUI 包管理器。
|
||||
|
||||
它仍然是 [Xfce 桌面环境][9]上的推荐工具。
|
||||
|
||||
首先安装它：
|
||||
|
||||
```
|
||||
sudo apt install synaptic
|
||||
```
|
||||
|
||||
打开 Synaptic 并搜索包名称。查找标记为绿色的已安装软件包。右键单击它们，然后单击“标记为删除”。之后点击应用。
|
||||
|
||||

|
||||
|
||||
### 对你有帮助吗？
|
||||
|
||||
我非常乐意使用 apt 命令删除从 .deb 文件中安装的软件包。但我可以理解，并不是每个人都喜欢使用命令行。
|
||||
|
||||
在删除从外部 deb 文件安装的应用时，我发现软件中心中缺失。它可以在这里做得更好。
|
||||
|
||||
我希望你现在对删除 deb 包有更好的了解。如果你有任何问题，请告诉我。
