软件中心根本打不开错误

Question

当我从菜单打开软件时，它说“无法打开软件数据库。请重新安装软件中心包。当我在终端上编写软件中心时，出现这样的错误：

2014-05-28 09:11:20,584 - softwarecenter.ui.gtk3.app - INFO - setting up proxy 'None'
2014-05-28 09:11:20,593 - softwarecenter.ui.gtk3.app - ERROR - xapian open failed

_xapian.Database_swiginit(self,_xapian.new_Database(*args))
DatabaseCorruptError: /var/cache/software-center/xapian/iamchert: Chert version file should be 28 bytes, actually 0

现在，当我写命令时 sudo apt-get remove software-center

dpkg: error: corrupt info database format file '/var/lib/dpkg/info/format'
E: Sub-process /usr/bin/dpkg returned an error code (2)

我之前有过 ubuntu，但它有点损坏了。现在，我重新安装了它，即使在开始时，软件中心也没有打开，并且出现此错误。我希望你有一个解决方案。谢谢。

缓存文件已损坏。要重新生成它，请打开终端并输入以下内容：

sudo rm -r /var/cache/software-center/xapian
sudo mv /var/lib/dpkg/info/format /var/lib/dpkg/info/format.bak
sudo dpkg --clear-avail
sudo apt-get update
sudo apt-get install --reinstall software-center
