试图安装MATE桌面环境，变得“无法纠正问题，您已经持有破碎的软件包”。

Question

就像标题说的，我试着用终端安装MATE桌面环境，我在http://wiki.mate-desktop.org/download上使用wiki指令--但是每次我输入"sudo apt-get install mate-core"，我就会陷入这样的境地。

username@computer:~$ sudo apt-get install mate-core

我不太清楚这意味着什么，因为我是Ubuntu..can的一个完全的菜鸟，有人帮助我吗？

这意味着安装mate-core所需的其他软件在服务器上不可用。尝试运行这些命令: sudo add-apt-存储库"deb http://packages.mate-desktop.org/repo/ubuntu精确主“&& sudo apt-get更新& sudo apt-get & sudo apt-get安装伙伴-core。
