Install Privacy-friendly WhatsApp Alternative Signal on Linux Desktop
|
|
||||||
======
|
|
||||||
|
|
||||||
It’s been more than a year [since we covered Signal as an ideal choice for instant messaging][1]. While privacy-aware and tech-savvy people were already aware of the existence of this awesome application, [Signal][2] got the much deserved fame after the latest WhatsApp privacy policy updates.
|
|
||||||
|
|
||||||
Whatever maybe the reason if you are new to Signal and you are wondering if you can use Signal on desktop, the answer is yes. You can install Signal on Linux, Windows and macOS systems along with your smartphone.
|
|
||||||
|
|
||||||
![Signal Messenger on Pop OS Linux distribution][3]
|
|
||||||
|
|
||||||
I am not going to highlight the features Signal offers because you might already be aware of them. I am going to show you different methods of installing Signal application Linux desktop:
|
|
||||||
|
|
||||||
* Install Signal on Linux using Snap (snap applications take longer to load but get automatic update and hassle-free installation)
|
|
||||||
* Install Signal on Debian and Ubuntu-based distributions using apt (additional efforts in adding the repository but installed apps get automatic updates)
|
|
||||||
* Install Signal on Arch and Manjaro Linux using AUR
|
|
||||||
* Install Signal on Fedora and other Linux using Flatpak package
|
|
||||||
|
|
||||||
|
|
||||||
|
|
||||||
You can choose one of the methods based on your distribution and preference:
|
|
||||||
|
|
||||||
### Method 1: Installing Signal on Ubuntu and other Linux using Snap
|
|
||||||
|
|
||||||
If you are using Ubuntu, you can find Signal desktop app in Snap package format in the Software Center.
|
|
||||||
|
|
||||||
![][4]
|
|
||||||
|
|
||||||
Alternatively, you can [use the Snap command][5] to install Signal on any [Linux distribution that has Snap support][6] enabled.
|
|
||||||
|
|
||||||
```
|
|
||||||
sudo snap install signal-desktop
|
|
||||||
```
|
|
||||||
|
|
||||||
You can remove it using `snap remove` or from the Software Center.
|
|
||||||
|
|
||||||
Some people do not like Snap packages because they take too long to start. The good news is that you can use apt command to install Signal. The next section discusses that.
|
|
||||||
|
|
||||||
### Method 2: Install Signal on Debian and Ubuntu-based distributions via APT (using official Signal repository)
|
|
||||||
|
|
||||||
Here are the steps you have to follow to install Signal from its official repository on Debian, Debian, Linux Mint, elementary OS and other distributions based on Debian/Ubuntu. You can [copy the commands and paste it in the terminal][7].
|
|
||||||
|
|
||||||
First thing is to get the GPG key for the official Signal repository and add it to the trusted keys of your APT package manager.
|
|
||||||
|
|
||||||
```
|
|
||||||
wget -O- https://updates.signal.org/desktop/apt/keys.asc | sudo apt-key add -
|
|
||||||
```
|
|
||||||
|
|
||||||
With the key added, you can safely add the repository to your system. _**Don’t get alarmed with the use of xenial in the repository name**_. It will work with Ubuntu 18.04, 20.04 and newer version as well as Debian, Mint etc.
|
|
||||||
|
|
||||||
```
|
|
||||||
echo "deb [arch=amd64] https://updates.signal.org/desktop/apt xenial main" | sudo tee -a /etc/apt/sources.list.d/signal-xenial.list
|
|
||||||
```
|
|
||||||
|
|
||||||
Thanks to the [tee command in Linux][8], you’ll have a new file `signal-xenial.list` in the sources.list directory `/etc/apt/sources.list.d`. This new file will have the Signal repository information i.e. `deb [arch=amd64] https://updates.signal.org/desktop/apt xenial main`.
|
|
||||||
|
|
||||||
Now that you have added the repository, update the cache and install Signal desktop application:
|
|
||||||
|
|
||||||
```
|
|
||||||
sudo apt update && sudo apt install signal-desktop
|
|
||||||
```
|
|
||||||
|
|
||||||
Once installed, look for Signal in application menu and start it.
|
|
||||||
|
|
||||||
![][9]
|
|
||||||
|
|
||||||
Since you have added the repository, your installed Signal application will be automatically updated with the regular system updates.
|
|
||||||
|
|
||||||
Enjoy encrypted messaging with Signal on your Linux desktop.
|
|
||||||
|
|
||||||
#### Removing Signal
|
|
||||||
|
|
||||||
The tutorial won’t be complete if I don’t share the removal steps with you. Let’s go through it.
|
|
||||||
|
|
||||||
First, remove the application:
|
|
||||||
|
|
||||||
```
|
|
||||||
sudo apt remove signal-desktop
|
|
||||||
```
|
|
||||||
|
|
||||||
You may leave it as it is, or you may remove the Signal repository from your system. It’s optional and up to you. With the repository still in the system, you can install Signal again, easily. If you remove the repository, you’ll have to add it again following the steps in the previous section.
|
|
||||||
|
|
||||||
If you want to remove the Signal repository as well, you can opt for the graphical method by going to Software and Updated tool and deleting it from there.
|
|
||||||
|
|
||||||
![][10]
|
|
||||||
|
|
||||||
Alternatively, you can remove the file with rm command:
|
|
||||||
|
|
||||||
```
|
|
||||||
rm -i /etc/apt/sources.list.d/signal-xenial.list
|
|
||||||
```
|
|
||||||
|
|
||||||
### Method 3: Installing Signal on Arch and Manjaro from AUR
|
|
||||||
|
|
||||||
Signal is available to install on [Arch-based Linux distributions][11] via [AUR][12]. If you are using Pamac on Manjaro and have enabled AUR, you should find Signal in the package manager.
|
|
||||||
|
|
||||||
Otherwise, you can always [use an AUR helper][13].
|
|
||||||
|
|
||||||
```
|
|
||||||
sudo yay -Ss <package-name>
|
|
||||||
```
|
|
||||||
|
|
||||||
I believe you can delete Signal in the similar function.
|
|
||||||
|
|
||||||
### Method 4: Installing Signal on Fedora and other Linux using Flatpak
|
|
||||||
|
|
||||||
There is no .rpm file for Signal. However, a [Flatpak package is available][14], and you may use that to get Signal on Fedora.
|
|
||||||
|
|
||||||
```
|
|
||||||
flatpak install flathub org.signal.Signal
|
|
||||||
```
|
|
||||||
|
|
||||||
Once installed, you can run it from the menu or use the following command in the terminal:
|
|
||||||
|
|
||||||
```
|
|
||||||
flatpak run org.signal.Signal
|
|
||||||
```
|
|
||||||
|
|
||||||
Signal and Telegram are two mainstream and viable options to ditch WhatsApp. Both provide native Linux desktop applications. If you use Telegram, you can [join the official It’s FOSS channel][15]. I use Signal in individual capacity because it doesn’t have the ‘channel’ feature yet.

在Linux桌面上安装隐私友好的WhatsApp替代品软件Signal
|
||||||
|
======
|
||||||
|
|
||||||
|
即时通讯软件Signal作为我的理想选择有一年多了。具有隐私意识的人和技术牛人已经意识到这个厉害软件的存在，与此同时，在最近的WhatsApp隐私政策更新之后，Signal更是得到了很多人的褒奖。
|
||||||
|
|
||||||
|
无论什么原因，如果你对Signal一无所知，同时你想知道是否能在桌面上使用Signal，答案是肯定的。你可以在Linux，Windows和macOS系统以及智能手机上安装Signal。
|
||||||
|
|
||||||
|
|
||||||
|
![Signal Messenger on Pop OS Linux distribution][3]
|
||||||
|
|
||||||
|
我不想强调Sinal的功能，因为你可能已经有所了解。我只想向你展示在Linux桌面上安装Signal的不同方法：
|
||||||
|
|
||||||
|
* 用Snap包管理器在Liunx上安装Sigal (除自动更新和无障碍安装之外，snap程序会加载很长时间)
|
||||||
|
* 用apt包管理器在Debian和基于Ubuntu的发行版上安装Signal(除了安装程序并自动更新外，还有添加仓库额外的操作)
|
||||||
|
* 用AUR包管理器在Arch和Manjaro Linux上安装Signal
|
||||||
|
* 用Flatpak包在Fedora和其他Linux系统上安装Signal
|
||||||
|
|
||||||
|
|
||||||
|
你可以基于你的发行版和偏好来选择这些安装方法的其中一种：
|
||||||
|
|
||||||
|
|
||||||
|
### 方法 1:用Snap包管理器在Liunx上安装Signal
|
||||||
|
|
||||||
|
如果你正在使用Ubuntu，你可以在软件中心找到Signal桌面版程序的Snap格式软件包。
|
||||||
|
|
||||||
|
![][4]
|
||||||
|
|
||||||
|
或者，你可以在任何[有Snap包支持功能的Linux发行版][6]上[使用Snap命令][5]安装Signal。
|
||||||
|
|
||||||
|
```
|
||||||
|
sudo snap install signal-desktop
|
||||||
|
```
|
||||||
|
|
||||||
|
你可以使用`snap remove` 命令或者从软件中心删除它。
|
||||||
|
|
||||||
|
有些人不喜欢Snap包是因为它们启动时间太长。好消息是你能够使用apt命令来安装Signal。下一部分我们再讨论。
|
||||||
|
|
||||||
|
|
||||||
|
### 方法 2: 通过APT在Debian和基于Ubuntu的发行版上安装Signal (使用官方Signal仓库)
|
||||||
|
|
||||||
|
这里是你必须在Debian，Linux Mint,elementary OS 和基于Debian/Ubuntu的其他发行版跟从安装Signal的步骤。你可以[在终端里复制和粘贴命令][7]。
|
||||||
|
|
||||||
|
第一件事是得到官方Signal仓库的GPG密钥，并且把它加入到你的APT包管理器可信任的密钥中。
|
||||||
|
|
||||||
|
```
|
||||||
|
wget -O- https://updates.signal.org/desktop/apt/keys.asc | sudo apt-key add -
|
||||||
|
```
|
||||||
|
|
||||||
|
密钥添加之后，你可以将仓库安全的添加的你的系统中。 _**不要因为仓库名称使用xenial惊慌失措**_。它将适配Ubuntu18.04，20.04和更新的版本以及Debian，Mint等等系统。
|
||||||
|
|
||||||
|
```
|
||||||
|
echo "deb [arch=amd64] https://updates.signal.org/desktop/apt xenial main" | sudo tee -a /etc/apt/sources.list.d/signal-xenial.list
|
||||||
|
```
|
||||||
|
|
||||||
|
多亏了 [Linux的tee命令][8],在sources.list目录`/etc/apt/sources.list.d`下你将会有一个叫做 `signal-xenial.list`的新文件。这个新文件有Signal仓库信息即`deb [arch=amd64] https://updates.signal.org/desktop/apt xenial main`。
|
||||||
|
|
||||||
|
|
||||||
|
既然你已经添加了仓库，那么来更新缓存并安装Signal桌面程序吧：
|
||||||
|
|
||||||
|
|
||||||
|
```
|
||||||
|
sudo apt update && sudo apt install signal-desktop
|
||||||
|
```
|
||||||
|
|
||||||
|
一旦安装成功，在程序菜单找到Signal然后启动它。
|
||||||
|
|
||||||
|
![][9]
|
||||||
|
|
||||||
|
由于你已经添加了仓库，你安装的Signal程序将会伴随系统日常更新而自动更新。
|
||||||
|
|
||||||
|
享受在Linux桌面上使用Signal加密通讯的乐趣吧。
|
||||||
|
|
||||||
|
#### 删除Signal
|
||||||
|
|
||||||
|
如果我不分享给你删除的步骤，那么指南是不完整的。让我们看一下。
|
||||||
|
|
||||||
|
首先，删除程序：
|
||||||
|
|
||||||
|
```
|
||||||
|
sudo apt remove signal-desktop
|
||||||
|
```
|
||||||
|
|
||||||
|
你可以保持原样，或者你可以从系统中删除Signal仓库。对你来说是可选择的。仓库继续在系统里的话，你可以轻松的再次安装Signal。如果你删除了仓库的话，你将不得不按照之前的步骤再次重新添加仓库。
|
||||||
|
|
||||||
|
如果你也想同时删除掉Signal仓库，你可以选择图形化方法，通过软件和更新工具在那里删除它。
|
||||||
|
|
||||||
|
![][10]
|
||||||
|
|
||||||
|
或者，你可以用rm命令来删除这个文件：
|
||||||
|
|
||||||
|
```
|
||||||
|
rm -i /etc/apt/sources.list.d/signal-xenial.list
|
||||||
|
```
|
||||||
|
|
||||||
|
### 方法 3:用AUR包管理器在Arch和Manjaro Linux上安装Signal
|
||||||
|
|
||||||
|
通过[AUR包管理器][12]在 [基于Arch的Linux发行版][11上安装Signal是有效的。如果你在Manjaro上使用Pamac并且启用了AUR包管理器，在包管理器里你可以找到Signal。
|
||||||
|
|
||||||
|
|
||||||
|
否则，你可以经常[使用AUR的帮助][13]。
|
||||||
|
|
||||||
|
```
|
||||||
|
sudo yay -Ss <package-name>
|
||||||
|
```
|
||||||
|
|
||||||
|
我相信你能够在相似的功能下删除店Signal。
|
||||||
|
|
||||||
|
### 方法 4: 用Flatpak包在Fedora和其他Linux系统上安装Signal
|
||||||
|
|
||||||
|
Signal没有.rpm的安装文件。然而，[Flatpak包是可用的][14],并且你可以在Fedora上用它来安装Signal。
|
||||||
|
|
||||||
|
|
||||||
|
```
|
||||||
|
flatpak install flathub org.signal.Signal
|
||||||
|
```
|
||||||
|
|
||||||
|
一旦安装成功，你可以从菜单中运行它或者在终端中输入以下命令：
|
||||||
|
|
||||||
|
```
|
||||||
|
flatpak run org.signal.Signal
|
||||||
|
```
|
||||||
|
|
||||||
|
|
||||||
|
Signal和Telegram是抛弃掉WhatsApp的两个主流和独立的可选软件。这两个软件都提供本地的Linux桌面程序。如果你使用Telegram，你可以[加入It’s FOSS的官方频道][15]。我个人来说使用Signal，因为它没有‘频道’这个功能。
