06-25 ubuntu12.04安装tftp、cache文件夹下没有software-center文件。后软卸载重装：
sudo apt-get autoremove software-center --purge
显示：
rmdir: 删除 “/var/cache/software-center/xapian/” 失败: 没有那个文件或目录
dpkg：处理 software-center (--purge)时出错：
子进程 已安装 post-removal 脚本 返回了错误号 1
在处理时有错误发生：
software-center
E: Sub-process /usr/bin/dpkg returned an error code (1)
查找了一下，中解决
sudo mkdir /var/cache/software-center
sudo mkdir /var/cache/software-center/xapian
sudo apt-get autoremove software-center --purge
sudo apt-get install software-center
一切正常。结果今天更新了系统重启后，
gongstring@chz-desktop:~$ software-center

解决办法如下：
sudo gedit /etc/lsb-release （好吧，
