卧槽 仔细看大脑一片空白啊 卧槽

谷歌了一把 真的不能瞎折腾 这是第二次第二次误删了

我也遇到了，ubuntu16.04系统，卸载了python3.5，导致了很多问题，后来解决了，找了另外一台机器将老的文件复制过去恢复了系统的python3.5。将下面网盘里的文件解压后放在:/usr/lib/python3/dist-packages/ 链接:https://pan.baidu.com/s/1g9gbOEG1MSr-4T3xWW6wSw

卧槽这个也没了 这度娘超级不靠谱啊
Failed to start apt-news.service: Unit apt-news.service not found.
Failed to start esm-cache.service: Unit esm-cache.service not found.

What are the services 'apt-news' and 'esm-cache', and how do I disable them?

注意正确解决方法来了

使用sudo aptitude install xxx代替sudo apt-get install xxx，但是注意，一般aptitude安装时候第一次推荐给你的方案都是没有改变原有依赖关系的，所以第一次提示你输入y还是n的时候，需要你输入
n，第二次才会给你具体处理依赖的方法，如降级等，如图，便可以完美解决依赖关系啦。
