一、前言

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.

dpkg: error processing package dukto (--install):

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
