KRDC报错：libQt5Core.so.5 No such file or directory
因为昨天烧坏了交换机，所以每次车轮出现错误运动按下驱动器断电按钮后，都要重新插拔网线，很不方便，反正都是直接重新切回Run模式，直接在Ubuntu远程连接倍福Windows桌面不是更方便
sudo krdc
报错如下
krdc: error while loading shared libraries: libQt5Core.so.5: cannot open shared object file: No such file or directory
CSDN的方法解决不了
error while loading shared libraries: libQt5Core.so.5: cannot open shared object file: No such file
strip --remove-section=.note.ABI-tag /usr/lib/x86_64-linux-gnu/libQt5Core.so.5
我/usr/lib/x86_64-linux-gnu/并没有libQt5Core.so.5这个动态库，建立软链接也没用
sudo ln -s /usr/lib/x86_64-linux-gnu/libQt5Core.so /usr/lib/x86_64-linux-gnu/libQt5Core.so.5
考虑可能是装的时候出了些问题，参考下面提问中的讨论
Ubuntu 18.4 libQt5Core.so.5: cannot open shared object file: No such file or directory
尝试重新安装，问题解决
sudo apt install --reinstall libqt5widgets5 libqt5gui5 libqt5dbus5 libqt5network5 libqt5core5a
