### 在 Linux 上安装 LiVES 视频编辑器


LiVES 几乎可以在所有主要的 Linux 发行版中使用。但是，你可能并不能在软件中心找到它的最新版本。所以，如果你想通过这种方式安装，那你就不得不耐心等待了。


如果你想要手动安装，可以从它的下载页面获取 Fedora/Open SUSE 的 RPM 安装包。它也适用于其他 Linux 发行版。


* [下载 LiVES 视频编辑器](http://lives-video.com/index.php?do=downloads#binaries)


如果你使用的是 Ubuntu（或其他基于 Ubuntu 的发行版），可以安装由 [Ubuntuhandbook](http://ubuntuhandbook.org/index.php/2019/08/lives-video-editor-3-0-released-install-ubuntu/) 维护的[非官方 PPA](https://itsfoss.com/ppa-guide/)。


下面由我来告诉你，你该做些什么：


1、启动终端后输入以下命令：



```
sudo add-apt-repository ppa:ubuntuhandbook1/lives
```

系统将提示你输入密码用于确认添加 PPA。


2、完成后，你现在可以轻松地更新软件包列表并安装 LiVES 视频编辑器。以下是需要你输入的命令段：



```
sudo apt update

3、现在，它开始下载并安装这个视频编辑器，等待大约一分钟即可完成。


### 总结


Linux 上有许多[视频编辑器](https://itsfoss.com/best-video-editing-software-linux/)。但它们通常被认为不能用于专业编辑。而我并不是一名专业人士，所以像 LiVES 这样免费的视频编辑器就足以进行简单的编辑了。

OK
We recently covered a list of [best open source video editors](https://itsfoss.com/open-source-video-editors/). LiVES is one of those open source video editors, available for free.

Even though a lot of users are still waiting for the release on Windows, a major update just popped up for LiVES Video Editor (i.e v3.0.1 as the latest package) on Linux. The new upgrade includes some new features and improvements.

In this article, I’ll cover the key improvements in the new version and I’ll also mention the steps to install it on your Linux system.

While some of the points listed can just go over your head if you are not an advanced video editor. But, in a nutshell, all of these things make ‘LiVES Video Editor’ a better open source video editing software.

## Installing LiVES Video Editor on Linux

LiVES is normally available in the repository of all major Linux distributions. However, you may not always find the latest version in your software center.

### Installing LiVES on Ubuntu

On Ubuntu 20.04, you already have LiVES 3.0 in the universe repository. You can install it either from the software center?

![Lives Video Editor Ubuntu](https://itsfoss.com/content/images/wordpress/2019/08/lives-video-editor-ubuntu.png)

Or use the command below:

`sudo apt install lives lives-plugins`


For Ubuntu 18.04 and Linux Mint 19 series, you can add the [unofficial PPA](https://itsfoss.com/ppa-guide/) maintained by [Ubuntuhandbook](http://ubuntuhandbook.org/index.php/2019/08/lives-video-editor-3-0-released-install-ubuntu/). Here’s how to do it:

**1.** Launch the terminal and enter the following command:

sudo add-apt-repository ppa:ubuntuhandbook1/lives

You will be prompted for the password to authenticate the addition of PPA.

**2. **Once done, you can now easily proceed to update the list of packages and get LiVES Video Editor installed. Here’s the set of commands that you need to enter next:

sudo apt update sudo apt install lives lives-plugins

**3.** Now, it will start downloading and installing the video editor. You should be good to go in a minute.

You should [know about removing PPA](https://itsfoss.com/how-to-remove-or-delete-ppas-quick-tip/) if you want to uninstall LiVES later.

### Installing LiVES on other Linux distributions

If you want to install it on other distributions, you can get the RPM packages for Fedora/Open SUSE from its download page.

The source code is also available for Linux distros.

**Wrapping Up**

There are a handful of [video editors available on Linux](https://itsfoss.com/best-video-editing-software-linux/). But they are not often considered good enough for professional editing. I am not a professional but I do manage simple editing with such freely available video editors like LiVES.
