ubuntu 16.04 apt-get upgrade 失败解决方法

在Ubuntu 16.04 下使用 apt-get upgrade 返回错误信息：

dpkg: error processing package initramfs-tools (--configure):
subprocess installed post-installation script returned error exit status 1
No apport report written because MaxReports is reached already

initramfs-tools
E: Sub-process /usr/bin/dpkg returned an error code (1)

搜索答案解决方法如下：

把/var/lib/dpkg/文件夹下的info做处理。命令如下：

$ sudo mv /var/lib/dpkg/info/ /var/lib/dpkg/info_old/
$ sudo mkdir /var/lib/dpkg/info/
$ sudo apt-get update
············
$ sudo mv /var/lib/dpkg/info/* /var/lib/dpkg/info_old/
$ sudo rm -rf /var/lib/dpkg/info
$ sudo mv /var/lib/dpkg/info_old/ /var/lib/dpkg/info/

执行上述操作之后，再进行update或者upgrade命令就不报错了。
