我们经常都需要通过局域网来传输各种文件/文件夹，从普通的电影、音乐、软件、学习材料、工作资料到大型的游戏、甚至是岛国的动作片等等，常常用Windows共享或QQ来传输都不是那么的方便。
Dukto 是一款非常简单实用的局域网文件传输工具，类似国内比较常用的飞鸽传书、飞秋等。而相比它们更出色，Dukto 完全免费开源，而且支持 Win、Mac、Linux、iOS、Android 等系统的跨平台传文件，拥有 Win8 的简约风格界面。只要电脑/手机们位于同一个局域网下 (不必连接互联网)，
但自从 工作机从Ubuntu18.04升级到Ubuntu20.04之后，发现dukto不能用了。安装的时候提示：
electing previously unselected package dukto. (Reading database ... 198333 files and directories currently installed.) Preparing to unpack dukto_6.0-1_amd64.deb ... Unpacking dukto (6.0-1) ... dpkg: dependency problems prevent configuration of dukto: dukto depends on libqt4-declarative (>= 4:4.7.0~rc1); however: Package libqt4-declarative is not installed. dukto depends on libqt4-network (>= 4:4.5.3); however: Package libqt4-network is not installed. dukto depends on libqtcore4 (>= 4:4.7.0~beta1); however: Package libqtcore4 is not installed. dukto depends on libqtgui4 (>= 4:4.6.1); however: Package libqtgui4 is not installed. dpkg: error processing package dukto (--install): dependency problems - leaving unconfigured Processing triggers for gnome-menus (3.36.0-1ubuntu1) ... Processing triggers for desktop-file-utils (0.24-1ubuntu3) ... Processing triggers for mime-support (3.64ubuntu1) ... Errors were encountered while processing: dukto
原因是dukto依赖libqt4，而Ubuntu20.04放弃了对libqt4的支持，转向更高的版本libqt5。
二、解决方案：安装libqt4安装
sudo add-apt-repository ppa:rock-core/qt4 sudo apt update sudo apt install libqtcore4三、ubuntu中的Dukto.deb的下载地址

四、安装sudo dpkg -i dukto_6.0-1_amd64.deb参考文献
