昨天（以及前几个月），我完全可以正常使用 Konsole。从那时起，我并没有刻意改变任何东西。然而，今天它却无法加载：
[11:06]~$ konsole
konsole: error while loading shared libraries: libQtSvg.so.4: cannot open shared object file: No such file or directory
[11:06]~$ locate libQtSvg.so.4
/usr/lib/x86_64-linux-gnu/libQtSvg.so.4
/usr/lib/x86_64-linux-gnu/libQtSvg.so.4.8
/usr/lib/x86_64-linux-gnu/libQtSvg.so.4.8.6
我也尝试了“okular”。我实际上没有使用任何其他 KDE 应用程序，但我认为这适用于所有应用程序。看起来库存在，但找不到。有什么想法可能导致这种情况，或者更重要的是如何修复它？
它可以很好地链接同一目录中的内容：

答案1
所以，我修复了这个问题。一堆 libQt 库都搞砸了。不知道是什么原因造成的。
已解决：
sudo apt-get install --reinstall libqt4-svg libqt4-script libqt4-scripttools libqt4-sql libqt4-test
