试图逃跑任何终端中的 apt-get 命令给出语法错误。Synaptic 和软件中心运行正常（Ubuntu 13.04）。
例如：
sudo apt-get install mpack
/usr/bin/apt-get: 1: /usr/bin/apt-get: Syntax error: end of file unexpected
错误发生时，我正在为网上银行安装 icedtea-7 java 浏览器插件，但不确定是否相关。有什么想法吗？
谢谢
更新：所有其他 sudo 命令看起来都很好。

修复 apt 问题的一个好开始通常是清理缓存并更新索引：$ sudo apt-get clean $ sudo apt-get update
如果问题仍然存在，则某些列表文件可能已损坏。手动删除它们然后更新索引可以解决该问题。
