有没有简单的方法来处理它？

我安装了midori：

$ sudo add-apt-repository --remove ppa:midori/ppa

但它在 Ubuntu 17.10 上不起作用，所以我必须删除它：

$ sudo ppa-purge ppa:midori/ppa
Updating packages lists
E: The repository 'http://ppa.launchpad.net/midori/ppa/ubuntu artful Release' does not have a Release file.
Warning:  apt-get update failed for some reason

知道为什么我不能删除它吗？

我努力了：

$ sudo add-apt-repository --remove ppa:midori/ppa

但仍然没有运气。

有任何想法吗？

编辑：

如果我这样做：

$ sudo add-apt-repository --remove ppa:midori/ppa

我得到：

它没有任何意义！

我已经安装了 Midori 以在 Elementary 模型中工作。Midori 工作得很好，但是在一些域上，它打开移动网站而不是常规页面。现在，这发生在 gmail.com、facebook.com、paginegialle.it 和其他网站上；还有其他有移动版本的网站，如 gazzetta.it，显示的是普通版本。我无法通过设置找到解决方案，也没有在论坛或其他地方找到任何提及此问题的内容，因此将不胜感激。
