我尝试在Debian桌面上运行owncloud客户端。我apt-get install owncloud-client这样做了。但是，当我owncloud在命令行上发出以下错误时：
This application failed to start because it could not find or load the
Qt platform plugin "xcb".
Available platform plugins are: linuxfb, minimal, minimalegl, offscreen.
Reinstalling the application may fix this problem.
但是当我从存储库安装软件包时，损坏的库依赖关系应该没有问题。验证我是否使用过ldd：
ldd /usr/bin/owncloud | grep xcb
输出：
libxcb.so.1 => /usr/lib/x86_64-linux-gnu/libxcb.so.1 (0x00007f190be16000)
libX11-xcb.so.1 => /usr/lib/x86_64-linux-gnu/libX11-xcb.so.1 (0x00007f190acd3000)

我还能怎么做才能找到问题？
