无法在Ubuntu 18.04 LTS上安装Midori浏览器

Question

我正在尝试将Midori安装到Ubuntu，首先是：

$ sudo add-apt-repository ppa:midori

答复是：

 Midori Browser
    http://twotoasts.de/index.php/midori/

This PPA is signed. To add the GPG key to your apt keyring:
   sudo apt-key adv --recv-keys --keyserver keyserver.ubuntu.com A69241F1
Starting with Karmic, adding the PPA and its key is as simple as:
   sudo add-apt-repository ppa:midori

You may also want to use the WebKit-team PPA:
     https://launchpad.net/~webkit-team/+archive/ppa
You can find unstable Midori versions at
    https://launchpad.net/~midori/+archive/midori-dev

有什么简单的方法能解决这个问题吗？

看起来PPA有点过时，但是Midori可以安装在64位仿生海狸上，如下所示：

sudo apt-get install libjavascriptcoregtk-1.0-0 libwebkitgtk-1.0-0
wget http://midori-browser.org/downloads/midori_0.5.11-0_amd64_.deb
sudo dpkg -i midori_0.5.11-0_amd64_.deb

正如下面的截图所示，这在我的仿生海狸VM上运行得很好：

请注意，这是一个旧的，也许不是很好维护的浏览器，所以要小心一点.
