升级的时候被我误中断了，重启后黑色的。如图
如果是因为1910升级到2004的那么只要安装ukui的环境就好了。我当时也是这样的，只不过我不是认为中断，而是系统卡了
lz输入一下dpkg -l | grep peony 看看输出结果~
~$ dpkg -l | grep peony

要重装？
从更新管理器可以继续更新吗？不行的话，sudo apt update 然后sudo apt upgrade看会报啥错
lz可以正常打开文件管理器吗？可以试试 sudo apt install peony
可以使用软件和更新这个东西把软件源换成别的，比如阿里云或者清华这些
看样子panel之类的其它组件也没升级。。。找个快点的源把ukui-desktop-environment装好再注销一下应该就差不多了
小白，不太会配置源，结果升级错了。已经重装了。
