请救，我今天准备在ubuntu软件中心安装一个glade开发工具，点击安装后，提示有一个守护进程发生错误，无法安装，具体提示如下：aptdaemon 中似乎有编程错误，该软件用于安装、卸载软件并且执行其他的软件包管理任务。Traceback (most recent call last):
File "/usr/lib/python2.7/dist-packages/aptdaemon/worker.py", line 972, in simulate
trans.unauthenticated = self._simulate_helper(trans)

pm.get_archives(fetcher, self._list, self._records)
SystemError: E:Method has died unexpectedly!, E:Sub-process returned an error code (100), E:Method /usr/lib/apt/methods/ did not start correctly
我去尝试安装其它程序也一样，请问是什么问题，该如何解决？

sudo apt-get install synaptic

我运行你的命令后，再去软件中心尝试，结果还是一样的。

用新力得删了软件中心

删了重装

sudo apt-get install software-center

下列【新】软件包将被安装：

升级了 0 个软件包，新安装了 1 个软件包，要卸载 0 个软件包，有 2 个软件包未被升级。

贴一下/etc/apt/sources.list 和 /etc/apt/sources.list.d 下的文件看看

那再试一下

sudo dpkg --configure -a

sudo apt-get install -f

还是不行，哎，见鬼了

个人认为，软件中心存在的价值在于教会用户如何卸载它

那就试下先把 libglade2-0 和 software-center 都卸载掉，可能是 libglade2-0 安装出错导致的。

话损了点儿，但有道理。pythin+gtk做的这个半残废实在该扔到代码垃圾堆里去。
