你这是版本混用导致的。从名称看，你这个软件是2015年的，带的库也是那个时候的，而且没有把依赖的Qt库带全，导致用了系统上新版本的libQt5DBus.so.5
你可以把它自带的libqxcb.so删掉，让它用和系统自带库配套的 /usr/lib/x86_64-linux-gnu/qt5/plugins/platforms/libqxcb.so

删掉了之后依然是报错

那就把系统上的/usr/lib/x86_64-linux-gnu/qt5/plugins/platforms/libqxcb.so 复制到/home/xxx/QSanguosha-v2-20150926/platforms/啊，反正核心思想就是要版本匹配，你照这个思路做呗。
如果它还自带有其他的Qt库也出这种问题，一样照此处理

程序我运行起来了。你需要加载一个旧版本的Qt库来运行
首先把压缩包重新解压一遍，把删掉的文件恢复。还是解压到~/QSanguosha-v2-20150926下面，然后运行下面的命令

代码：全选

mkdir /tmp/qt
wget http://mirrors.aliyun.com/ubuntu/pool/main/q/qtbase-opensource-src/libqt5gui5_5.5.1+dfsg-16ubuntu7.7_amd64.deb  -O /tmp/qt/a.deb
dpkg-deb -x /tmp/qt/a.deb /tmp/qt
mv /tmp/qt/usr/lib/x86_64-linux-gnu/libQt5XcbQpa.so.5.5.1 ~/QSanguosha-v2-20150926/libQt5XcbQpa.so.5
rm -r /tmp/qt

要运行程序的时候预先加载它即可

代码：全选

cd ~/QSanguosha-v2-20150926
LD_PRELOAD=./libQt5XcbQpa.so.5 ./QSanguosha
