昨天在ubuntu的中安装了一下“Python版webqq客户端”程序，

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。法打

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，办法

gongstring@chz-desktop:~$ software-center

Traceback (most recent call last):

ImportError: No module named LinuxDeepin

解决办法如下：

sudo gedit /etc/lsb-release     （好吧，cache文件夹下没有software-center文件。后软配置tftp服务 错误解决方案
