本文介绍如何在Ubuntu 22.04 Linux系统上安装Opera Web浏览器的方法。

在Ubuntu 22.04上安装Opera的详细步骤

步骤1：将Opera APT存储库添加到Ubuntu 22.04

基于Debian的系统提供了一个包含Opera Web浏览器最新版本的APT存储库。在添加存储库之前，让我们导入存储库GPG密钥：

sudo apt update && sudo apt install wget curl

wget -qO- https://deb.opera.com/archive.key | sudo apt-key add -

curl https://deb.opera.com/archive.key | gpg --dearmor > opera.gpg

sudo install -o root -g root -m 644 opera.gpg /etc/apt/trusted.gpg.d/

GPG密钥将添加到/etc/apt/trusted.gpg.d/目录中：

$ ls /etc/apt/trusted.gpg.d/

opera.gpg  ubuntu-keyring-2012-cdimage.gpg  ubuntu-keyring-2018-archive.gpg

安装software-properties-common包，该包提供add-apt-repository，用于将Opera存储库添加到我们的Ubuntu Linux：

sudo apt install lsb-release ca-certificates apt-transport-https software-properties-common -y

使用add-apt-repository命令添加Opera存储库：

sudo add-apt-repository "deb [arch=i386,amd64] https://deb.opera.com/opera-stable/ stable non-free"

步骤2：在Ubuntu 22.04上安装Opera Web浏览器

添加存储库后，通过从所有配置的源下载包信息来确认它是否正常工作：

$ sudo apt update

Get:1 http://security.ubuntu.com/ubuntu jammy-security InRelease [90.7 kB]

Hit:2 https://deb.opera.com/opera-stable stable InRelease

Hit:3 http://ke.archive.ubuntu.com/ubuntu jammy InRelease

Ign:4 http://repo.vivaldi.com/stable/deb stable InRelease

Hit:5 http://repo.vivaldi.com/stable/deb stable Release

Get:6 http://ke.archive.ubuntu.com/ubuntu jammy-updates InRelease [90.7 kB]

Get:8 http://ke.archive.ubuntu.com/ubuntu jammy-backports InRelease [90.7 kB]

现在在Ubuntu 22.04上安装Opera web浏览器：

sudo apt install opera-stable

检查依赖项，然后按键盘上的y或yes继续安装：

同意“是否要与系统的其他部分一起更新Opera？（Do you want to update Opera together with the rest of the system）”：

可以使用apt命令检查包括版本号在内的已安装软件包详细信息：

$ apt policy opera-stable

它会返回相关版本的信息。

步骤3：在Ubuntu 22.04上使用Opera Web浏览器

可从终端启动已安装的Opera浏览器：

$ opera

或从桌面环境应用程序搜索：

打开后，即表明我们已经在Ubuntu 22.04桌面系统上完成了Opera Web浏览器的安装：

当然，用户也可以将Opera设置成默认的浏览器，以替代Firefox使用。
