package libkf5style5:amd64 5.68.0-0ubuntu1 failed to install/upgrade: 该软件包正处于非常不稳定的状态； 您最好在配置它之前，先重新安装它

[Wang Xinyu]

When I executed the command "sudo apt install plasma desktop" on the terminal, I interrupted it. After that, I typed "sudo dpkg -- configure - a" to try to continue the installation, but I encountered this error. I tried to install or uninstall the software package "libkf5style5: AMD64", but the terminal displayed "dpkg: processing package libkf5style5: AMD64 (- - configure)":
The software package is in a very unstable state;
You'd better re install it before you configure it
An error occurred during processing:
libkf5style5:amd64
E: Sub-process /usr/bin/dpkg returned an error code (1)”
I am running Ubuntu20.04.1.
