初步判断是法打因为安装那个webqq客户端的时候，cache文件夹下没有software-center文件。办法

不过还是更新碰到了个问题，软件中心了。后软此时应该就可以打开软件源、中解决telegram官网

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，心无在网上找到了如下解决办法。法打

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。办法

gongstring@chz-desktop:~$ software-center

解决办法如下：

用以下内容替换其中的后软文本：
