是否有方法在Ubuntu19.04中安装Deepin桌面环境？

Question

我最近尝试安装Deepin桌面环境(DDE)在新发布的Ubuntu 19.04.但失败了。我使用了命令sudo add-apt-repository ppa:leaeasy/dde并获得了以下错误：

我搜索了它们，在互联网上找不到任何关于这些错误的信息，而且我对linux还比较陌生。如有任何帮助，将不胜感激。

转到“软件和更新”，转到“其他软件”选项卡，删除刚才添加的存储库。然后退出它，您应该能够运行"apt update“而没有错误。

糟糕的是，如果没有一些严肃的手工操作，就无法在19.04上安装Deepin。希望PPA所有者能解决这个问题。
