无法在 Ubuntu 17.04 上安装 Opera 浏览器

Question

我试图通过.deb从歌剧网站下载文件来安装歌剧。运行sudo dpkg -i opera-stable_44.0.2510.1218_amd64得到以下结果：

[sudo] password for user1:

Opera 目前在 Ubuntu 软件商店或 Software Boutique 中不可用。我也试过更老的opera-stable_44.0.2510.857_amd64.deb，得到了类似的结果。我下载了两次包，认为它可能是任何下载错误，但结果相同。

尝试这个：

打开终端，

按Ctrl+ Alt+T

运行：

exec sudo -i
nano /etc/apt/sources.list.d/opera-stable.list

在打开的文件中，粘贴以下文本：

# This file makes sure that Opera Browser is kept up-to-date
# as part of regular system upgrades

deb https://deb.opera.com/opera-stable/ stable non-free #Opera Browser (final releases)

Ctrl+O

保存存档。

Ctrl+X

关闭纳米。

继续在终端运行：

wget -O - http://deb.opera.com/archive.key | apt-key add -
apt-get update
apt-get install opera-stable
