使用阿里的云出现：
dpkg: 处理软件包 inittramfs-tools (–configure)时出错
子进程 已安装 post-installation 脚本 返回错误状态1
如图
后面换成清华的源，
update确实效果好很多，以为是清华的源比阿里的要好
结果我在安装QT输入法插件的时候又碰到这个问题
下面是清华的源地址：

deb-src http://mirrors.aliyun.com/ubuntu/ bionic-backports main restricted universe multiverse替换方法：
首先进入到/etc/apt/目录下，把之前的source.list备份一下，然后把清华的源复制进去，保存。
最好，使用sudo apt-get update更新一下即可。
具体命令
$sudo cp /etc/apt/source.list /etc/apt/source.list-bak
$sudo vim /etc/apt/source.list
：wq保存退出
希望对你有帮助。
