E: Sub-process /usr/bin/dpkg returned an error code (1)解决办法 安装libapache2-svn出现了这个错误，是由于apt－get安装软件时出现了类似于：
dpkg: error processing package libapache2-mod-svn (--configure): subprocess installed post-installation script returned error exit status 1 No apport report written because the error message indicates its a followup error from a previous failure. dpkg: dependency problems prevent configuration of libapache2-svn: libapache2-svn depends on libapache2-mod-svn; however: Package libapache2-mod-svn is not configured yet.
dpkg: error processing package libapache2-svn (--configure): dependency problems - leaving unconfigured Errors were encountered while processing: libapache2-mod-svn libapache2-svn E: Sub-process /usr/bin/dpkg returned an error code (1) 1 2 3 4 5 6 7 8 9 10 11 12 13 解决方法： 现将info文件夹更名
sudo mv /var/lib/dpkg/info /var/lib/dpkg/info.bk 1 新建一个新的info文件夹
sudo mkdir /var/lib/dpkg/info 1 安装修复
sudo apt-get update $sudoapt-get install -f 1 2 执行完上一步操作后，在info文件夹下生成一些文件，现将这些文件全部移到info.bk文件夹下
sudo mv /var/lib/dpkg/info/* /var/lib/dpkg/info.bk 1 把自己新建的info文件夹删掉
sudo rm -rf /var/lib/dpkg/info 1 恢复原有info文件夹，修改名字
sudo mv /var/lib/dpkg/info.bk /var/lib/dpkg/info 1 到这里已经成功安装了，但我还遇到了相关文件的缺失，例如
/etc/apache2/mods-available/dav_svn.conf
但是现在至少能够正常安装了，直接索性卸载重装
sudo apt-get --purge remove libapache2-mod-svn sudo apt-get --purge remove libapache2-svn sudo apt-get autoremove 1 2 3 再install一边，恢复正常 ————————————————
