E: Sub-process /usr/bin/dpkg returned an error code (1) 解决办法

在 Ubuntu 执行 sudo apt-get install 时，出现了如下的报错：

Setting up ssh (1:7.6p1-4ubuntu0.3) ...

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

 

通过执行下面的命令可以解决该问题：

$ sudo mv /var/lib/dpkg/info/ /var/lib/dpkg/info_old/

$ sudo mkdir /var/lib/dpkg/info/

$ sudo apt-get update

$ sudo apt-get -f install

$ 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/

 

 

输入上述命令之后，在执行 sudo apt-get update 和 sudo apt-get upgrade 就不会有问题了。
