先在终端输入sudo apt update

如果有报错，截图贴上来

没有报错就在商店重新安装

不行啊，我试了下，所有软件包都是新的，我有试着安装了一下其他，还是不行。

商店显示已安装应用为0

打开商店装了个应用，安装失败，一样的报错，取消安装，关闭商店，日志在下面

用apt装看报错

apt list | grep scrcpy找不到，可能源里没有吧，但是应用商店里能找到，装不了，我寻思会不会是我少加了什么源

没有啊，你用的什么源

官方源。你是不是151升级上来源没换好？

我是上个月装的deepin系统,期间装其他软件换过源，但又换回来了，中间有次升级，升级后发现商店不能用了，我就把商店卸了，后来看到QQMusic出来了，我就想试试，发现源里没有，我就把商店又装上了

我能看看你的源吗

是不是把源玩坏了？

我是内测源

敢问版主deepin怎么备份

是不是把用户家目录做个备份就行了

基本裸奔，/home装的时候独立挂载，系统崩了不会影响，下次重装重新挂载，相同用户名就可以了
