我一直尝试通过安装 quasselapt并出现以下错误：
quassel: error while loading shared libraries: libQt5DBus.so.5: cannot open shared object file: No such file or directory
VLC 也存在非常类似的问题：
VLC media player 2.2.6 Umbrella (revision 2.2.6-0-g1aae78981c)
[0000562e813679d8] core libvlc: Running vlc with the default interface. Use 'cvlc' to use vlc without interface.
[0000562e8147ec68] skins2 interface error: no suitable dialogs provider found (hint: compile the qt4 plugin, and make sure it is loaded properly)
[0000562e8147ec68] skins2 interface error: cannot instantiate qt4 dialogs provider
[0000562e8147ec68] [cli] lua interface: Listening on host "*console".
VLC media player 2.2.6 Umbrella
Command Line Interface initialized. Type `help' for help.
我已尽力安装缺少的库，但似乎无法解决错误。
有没有人有什么建议？
