我尝试使用以下方法在我的Ubuntu 14.04上安装TreeSheets。
sudo gedit /etc/apt/sources.list
added : deb http://us.archive.ubuntu.com/ubuntu wily main universe
sudo apt-get update
sudo apt-get install treesheets
来源：http://installion.co.uk/ubuntu/wily/universe/t/treesheets/install/index.html
但是，我最终遇到了很多问题，（因为它适用于Ubuntu 15.04）然后我尝试使用以下命令解决我的问题：
sudo apt-get update
sudo apt-get install -f
sudo apt-get autoremove
sudo apt-get clean
但同样的错误，我也尝试了
sudo dpkg -a --configure
但是同样的错误如下：
