[问题]系统字体丢失，无论是下拉菜单还是桌面都是方块。

[plasma2006]

我想用7.04的源安装了新版的eva，于是找到7.04的源。
sudo apt-get update
sudo apt-get remove eva(6.06版本）
sudo apt-get install eva(7.04版本）
其中出现有更新、安装等。
安装后启动EVA，正常登录，但不能输入中文。
改7.04的源为6.06。
sudo gedit /apt/etc/source/sources.list出现如下的错误，并且终端的菜单变为方框。
保存6.06的源，sudo apt-get update
然后，新得立有两个更新。更新完毕，更毁了，连系统菜单及其下拉菜单，桌面文字都变为方框了。
大家快来救救我吧。谢谢

论坛有要求的，不要在标题写救命这样的哦。
标题要把要求写好，知道的人才会进来帮忙，你说是不。
改下吧。用eva的人才知道你是问这个软件哦。

用7.04的源在6.06上安装软件？太那个了吧……直接升级算了，要不就别用eva算了
