Method 1: Install LibreWolf via APT PPA

Update System Packages Before LibreWolf Installation

To start, it’s essential to ensure that your system’s existing packages are up to date. This helps minimize compatibility issues and keeps your system secure. Run the following commands in your terminal to update and upgrade your system packages:
首先，確保系統現有的套件是最新的至關重要。這有助於最大程度地減少相容性問題，並確保系統安全。在終端機中執行以下指令，更新和升級您的系統套件：

sudo apt update
sudo apt upgrade

Install Initial Packages For LibreWolf

Before installing LibreWolf, a few dependencies need to be installed. Most of these packages are likely already present on your system, but running the following command helps ensure that they are installed:
在安裝 LibreWolf 之前，需要安裝一些相依套件。這些套件大多數可能已經存在於您的系統上，但執行以下指令有助於確保它們已安裝：

sudo apt install curl apt-transport-https -y

If you encounter issues later, remember to return and run this command.
如果您之後遇到問題，請記得回頭執行此指令。

Import LibreWolf APT PPA

To securely install LibreWolf, you’ll first need to import the GPG key, which is used to verify the authenticity of the packages. Execute the following command in your terminal to import the key into your keychain:
為了安全地安裝 LibreWolf，您首先需要匯入 GPG 金鑰，該金鑰用於驗證套件的真實性。在終端機中執行以下指令，將金鑰匯入您的金鑰串：

curl -fsSl https://deb.librewolf.net/keyring.gpg | sudo gpg --dearmor | sudo tee /usr/share/keyrings/librewolf.gpg > /dev/null

After importing the GPG key, proceed to add the LibreWolf repository to your system’s sources:
匯入 GPG 金鑰後，繼續將 LibreWolf 軟體來源庫添加到您的系統軟體來源：

echo "deb [arch=amd64 signed-by=/usr/share/keyrings/librewolf.gpg] http://deb.librewolf.net $(lsb_release -sc) main" | sudo tee /etc/apt/sources.list.d/librewolf.list

Update the Packages List After LibreWolf APT PPA Import

Now that the LibreWolf repository has been added to your system, run an APT update to refresh the package list and include the newly imported repository:
由於 LibreWolf 軟體來源庫已添加到您的系統中，執行 APT 更新以刷新套件清單並包含新匯入的軟體來源庫：

sudo apt update

Finalize Installation of LibreWolf Browser via APT Command

At this point, your system is prepared to install the LibreWolf browser. To proceed, run the following command in your terminal:
至此，您的系統已準備好安裝 LibreWolf 瀏覽器。要繼續，請在終端機中執行以下指令：

sudo apt install librewolf

Method 2: Install LibreWolf via Flatpak and Flathub

This section will explore an alternative method for installing LibreWolf using the Flatpak package manager. Flatpak is a universal package management system for Linux similar to Snap. It provides a sandboxed environment, ensuring the applications are isolated from the rest of the system and enhancing security and stability. Installing LibreWolf with Flatpak ensures easy updates and compatibility across different distributions.
本節將探討使用 Flatpak 套件管理器安裝 LibreWolf 的另一種方法。Flatpak 是一種類似於 Snap 的 Linux 通用套件管理系統。它提供沙盒環境，確保應用程式與系統其他部分隔離，從而增強安全性和穩定性。使用 Flatpak 安裝 LibreWolf 可確保輕鬆更新並在不同發行版之間保持相容性。

Note: If your system does not have Flatpak installed, please refer to our guide on How to Install Flatpak on Ubuntu for step-by-step instructions on installing the most recent supported version of Flatpak.
注意：如果您的系統未安裝 Flatpak，請參閱我們的「如何在 Ubuntu 上安裝 Flatpak」指南，了解安裝最新支援版本的 Flatpak 的逐步說明。

Enable Flathub For LibreWolf

Before installing LibreWolf through Flatpak, you must enable the Flathub repository, a primary source for Flatpak applications. To enable Flathub, execute the following command in your terminal:
在透過 Flatpak 安裝 LibreWolf 之前，您必須啟用 Flathub 軟體庫，這是 Flatpak 應用程式的主要來源。要啟用 Flathub，請在您的終端機中執行以下指令：

sudo flatpak remote-add --if-not-exists flathub https://flathub.org/repo/flathub.flatpakrepo

This command adds the Flathub repository to your Flatpak configuration, ensuring you have access to various applications, including LibreWolf.
此命令會將 Flathub 儲存庫新增到您的 Flatpak 設定，確保您可以存取各種應用程式，包括 LibreWolf。

Install LibreWolf via Flatpak Command

With Flathub enabled, you can now install LibreWolf using the flatpak install command. Run the following command in your terminal:
啟用 Flathub 後，您現在可以使用 flatpak install 指令安裝 LibreWolf。在您的終端機中執行以下指令：

flatpak install flathub io.gitlab.librewolf-community -y

This command installs the LibreWolf browser from the Flathub repository, providing you with the latest version of the application.
此指令會從 Flathub 軟體庫安裝 LibreWolf 瀏覽器，提供您最新版本的應用程式。
