1. 命令行执行sudo apt-get --fix-broken install

2. 回忆是否使用chattr锁住了某些软件的文件

可以在终端使用命令更新  到时候可以看见报错。。。

这个绝对是官方的BUG，我两台电脑都是你这样，更新不了，后来看了论坛的建议，用命令行更新了

sudo apt update && sudo apt upgrade

sudo apt update && sudo apt upgrade看报错

不是bug.....有的更新要用到终端的，或者是之前没有更新完全导致出错

kirin@kirin:~$ sudo apt update && sudo apt upgrade
