Manage Flatpak Permission Using Flatseal
|
||||
======
|
||||
Learn how to manage Flatpak permission using the Flatseal app, which gives you a friendly GUI and additional features.
|
||||
|
||||
Installing applications can be challenging in Linux from a new user standpoint. The primary reason is there are so many [Linux distributions][1]. And you need different installation methods or instructions for various Linux distributions. It can be overwhelming for some users. In addition, it’s also difficult for developers to create separate packages and builds for different distributions.
|
||||
|
||||
### Flatpak solved this problem. How?
|
||||
|
||||
It uses container tech so that the same application executable runs similarly on all Linux platforms. For example, one single executable can run in Ubuntu, Fedora, OpenSUSE, Arch Linux and many others.
|
||||
|
||||
Moreover, the developers also spend fewer efforts on packaging the same app for different platforms. And they can concentrate on the app features rather than the distributions or deployments.
|
||||
|
||||
In addition, Flatpak apps also get updates instantly, and you get the newest version as soon as it’s available.
|
||||
|
||||
All these benefits also open up an important question. What is the permission a Flatpak app needs? How do you manage them easily? For example, one app may require only network access, not disk space. Or another may have access to take screenshots, but it might not be required at all.
|
||||
|
||||
So, it is essential to review the permission of a Flatpak app. This is similar to your Android or iOS app permission.
|
||||
|
||||
Finally, even if you are a new user, it’s not that difficult to manage and review the permissions, thanks to the graphical app – Flatseal.
|
||||
|
||||
### What is Flatseal?
|
||||
|
||||
Flatseal is a Flatpak application which gives you a friendly user interface to view and change permissions of all the Flatpak apps in your system.
|
||||
|
||||
It is an excellent little app with an easy-to-use toggle button for each of the permission sections per application. Here’s how it looks (Figure 1).
|
||||
|
||||
![Figure 1 – Flatseal App][2]
|
||||
|
||||
### How do you use Flatseal to manage Flatpak Permission?
|
||||
|
||||
When opening the Flatseal app, it should list all the Flatpak apps at the left navigation bar. And once you select one application, it shows the available permission settings in the main window at the right.
|
||||
|
||||
Now, for each Flatpak permission control, the current value is shown in the toggle switch. If the permission is in use, it should be set. Otherwise, it should be greyed out.
|
||||
|
||||
First, to set permission, you must navigate to your system’s application. Then, you can enable or disable any respective control from the permission list.
|
||||
|
||||
Second, if you want to set a global control that applies to all the Flatpak in your system, you can choose “All Applications” at the left-top and apply the global setting (Figure 2).
|
||||
|
||||
![Figure 2: Manage Flatpak Permission using Flatseal][3]
|
||||
|
||||
It’s super easy. Isn’t it?
|
||||
|
||||
### Example of Managing Flatpak Permission using Flatseal
|
||||
|
||||
Let’s take an example.
|
||||
|
||||
In my system, I have the above Flatpak installed (Figure 2). Let’s pick the Telegram Desktop app. Currently, the Telegram desktop does not have permission to access any home directory or user files (Figure 3).
|
||||
|
||||
![Figure 3: Telegram Desktop Flatpak App does not have permission to the home folders][4]
|
||||
|
||||
Now, if I want to permit all user files and any specific folder (e.g. /home/Downloads), you can give it by turning the enable switch on. See the Figure 4 below.
|
||||
|
||||
![Figure 4: Permission changed of Telegram Desktop to give access to folders][5]
|
||||
|
||||
Similarly, you can enable or disable the permission you want. Under the hood, Flatseal performs the internal Flatpak commands to achieve this.
|
||||
|
||||
For example, the above scenario may translate to the following command.
|
||||
|
||||
```
|
||||
flatpak override org.telegram.desktop --filesystem=/home/Downloads
|
||||
```
|
||||
|
||||
And to remove:
|
||||
|
||||
```
|
||||
flatpak override org.telegram.desktop --nofilesystem=/home/Downloads
|
||||
```
|
||||
|
||||
There is also another cool feature of Flatseal which shows a small alert icon beside the user-specific permission changes (See Figure 4).
|
||||
|
||||
### Can I install Flatseal in all Linux distributions?
|
||||
|
||||
Yes, you can install [Flatseal][6] in all Linux Distributions as Flatpak. You can set up your system using [this guide][7] and run the following command to install. Or, [click here][8] to launch the system-specific installer directly.
|
||||
|
||||
```
|
||||
flatpak install flathub com.github.tchx84.Flatseal
|
||||
```
|
||||
|
||||
### Closing Notes
|
||||
|
||||
I hope the above guide to managing Flatpak permission is easy enough for you to understand and start with Flatpak. It’s super easy to control and far easier to use. Also, you may want to visit our more Flatpak [guide here][9].

使用 Flatseal 管理 Flatpak 的权限
|
||||
======
|
||||
了解如何使用 Flatseal 应用管理 Flatpak 权限，它为你提供了一个友好的 GUI 和额外的功能。
|
||||
|
||||
从新用户的角度来看，在 Linux 中安装应用可能是一个挑战。主要原因是有这么多的 [Linux 发行版][1]。而你需要为各种 Linux 发行版提供不同的安装方法或说明。对于一些用户来说，这可能会让他们不知所措。此外，对于开发者来说，为不同的发行版创建独立的软件包和构建也很困难。
|
||||
|
||||
### Flatpak 解决了这个问题。如何解决？
|
||||
|
||||
它使用了容器技术，使同一个应用的可执行文件在所有的 Linux 平台上都能类似地运行。例如，一个单一的可执行文件可以在 Ubuntu、Fedora、OpenSUSE、Arch Linux 和许多其他平台上运行。
|
||||
|
||||
此外，开发人员还可以减少为不同平台打包同一应用的努力。他们可以专注于应用的功能，而不是发行或部署。
|
||||
|
||||
此外，Flatpak 应用还能即时更新，当有了最新版本，你就能得到它。
|
||||
|
||||
所有这些好处也开启了一个重要的问题。Flatpak 应用需要的权限是什么？你如何轻松地管理它们？例如，一个应用可能只需要网络访问，而不需要磁盘空间。或者另一个可能有截图的权限，但可能根本就不需要。
|
||||
|
||||
所以，审查一个 Flatpak 应用的权限是非常必要的。这与你的安卓或 iOS 应用的权限类似。
|
||||
|
||||
最后，即使你是一个新用户，管理和审查权限也不是那么困难，这要感谢图形化的应用 - Flatseal。
|
||||
|
||||
### 什么是 Flatseal？
|
||||
|
||||
Flatseal 是一个 Flatpak 应用，它为你提供了一个友好的用户界面来查看和改变你系统中所有 Flatpak 应用的权限。
|
||||
|
||||
它是一个优秀的小程序，每个应用的每个权限部分都有一个易于使用的切换按钮。下面是它的外观（图 1）。
|
||||
|
||||
![Figure 1 – Flatseal App][2]
|
||||
|
||||
### 你如何使用 Flatseal 来管理 Flatpak 的权限？
|
||||
|
||||
当打开 Flatseal 应用时，它应该在左边的导航栏列出所有的 Flatpak 应用。而当你选择了一个应用，它就会在右边的主窗口中显示可用的权限设置。
|
||||
|
||||
现在，对于每个 Flatpak 权限控制，当前值显示在切换开关中。如果该权限正在使用中，它应该被设置。否则，它应该是灰色的。
|
||||
|
||||
首先，要设置权限，你必须进入你的系统的应用。然后，你可以从权限列表中启用或禁用任何各自的控制。
|
||||
|
||||
其次，如果你想设置一个适用于你系统中所有 Flatpak 的全局控制，你可以在左上方选择“所有应用”并应用全局设置（图 2）。
|
||||
|
||||
![Figure 2: Manage Flatpak Permission using Flatseal][3]
|
||||
|
||||
这真是超级简单。不是吗？
|
||||
|
||||
### 使用 Flatseal 管理 Flatpak 权限的例子
|
||||
|
||||
让我们举个例子。
|
||||
|
||||
在我的系统中，我安装了上述 Flatpak（图 2）。让我们挑选 Telegram 桌面应用。目前，Telegram 桌面没有访问任何主目录或用户文件的权限（图 3）。
|
||||
|
||||
![Figure 3: Telegram Desktop Flatpak App does not have permission to the home folders][4]
|
||||
|
||||
现在，如果我想允许所有的用户文件和任何特定的文件夹（例如：/home/Downloads），你可以通过打开启用开关来给予它。请看下面的图 4。
|
||||
|
||||
![Figure 4: Permission changed of Telegram Desktop to give access to folders][5]
|
||||
|
||||
同样地，你可以启用或禁用你想要的权限。在内部，Flatseal 执行内部的 Flatpak 命令来实现这一点。
|
||||
|
||||
例如，上述情况可能转化为以下命令。
|
||||
|
||||
```
|
||||
flatpak override org.telegram.desktop --filesystem=/home/Downloads
|
||||
```
|
||||
|
||||
而要删除：
|
||||
|
||||
```
|
||||
flatpak override org.telegram.desktop --nofilesystem=/home/Downloads
|
||||
```
|
||||
|
||||
Flatseal 还有一个很酷的功能，它在用户特定的权限变化旁边显示一个小的警报图标（见图 4）。
|
||||
|
||||
### 我可以在所有的 Linux 发行版中安装 Flatseal 吗？
|
||||
|
||||
是的，你可以把 [Flatseal][6] 作为 Flatpak 安装在所有 Linux 发行版中。你可以使用[本指南][7]设置你的系统，并运行以下命令进行安装。或者，[点击这里][8]直接启动特定系统的安装程序。
|
||||
|
||||
```
|
||||
flatpak install flathub com.github.tchx84.Flatseal
|
||||
```
|
||||
|
||||
### 结束语
|
||||
|
||||
我希望上面的 Flatpak 权限管理指南足够简单，让你了解并开始使用 Flatpak。它超级容易控制，使用起来也容易得多。另外，你可能想访问我们更多的 [Flatpak 指南][9]。
