dpkg: 处理软件包 debconf (--configure)时出错：
installed debconf package post-installation script subprocess returned error exit status 2
在处理时有错误发生：
debconf
E: Sub-process /usr/bin/dpkg returned an error code (1)

解决方法：
1、下载perl-base_5.26.1-6ubuntu0.3_amd64.deb文件
2、下载debconf-doc_1.5.73_all.deb文件

上面这两个文件要从网页上下载，要看自己的Ubuntu版本，下载对应的版本
3、下载完之后，dpkg -i *.deb安装这两个包
4、安装完成之后，就可以正常使用apt-get了
