Hello Linux Geeksters. As you may know, CherryTree is a text editor, with the features of a modern editor, such as syntax highlighting, spell check, export to html, password protection, and many others. The latest version available is CherryTree 0.30.5, which has been released recently. For more information, see the official release announcement. 
In this article I will show you how to install CherryTree 0.30.5 on Ubuntu 13.10 Saucy Salamander, Ubuntu 13.04 Raring Ringtail, Ubuntu 12.10 Quantal Quetzal, Ubuntu 12.04 Precise Pangolin, Ubuntu 10.04 Lucid Lynx, Linux Mint 16 Petra, Linux Mint 15 Olivia, Linux Mint 14 Nadia, Linux Mint 13 Maya, Elementary OS 0.2 Luna, Debian, KWheezy and Crunchbang.
For the listed Ubuntu, Linux Mint, Pear OS and Elementary OS systems, CherryTree 0.30.5 is available via PPA, so installing it is easy. All you have to do is add the ppa to your system, update the local repository index and install the cherrytree package. Like this:
$ sudo add-apt-repository ppa:vincent-c/cherrytree
$ sudo apt-get update
$ sudo apt-get install cherrytree
There is no repository containing CherryTree 0.30.5 for Debian, Kwheezy and Crunchbag, so we have to download the deb package from the official site and install it with dpkg. Like this:
$ wget -c www.giuspen.com/software/cherrytree_0.30.5-1_all.deb
$ sudo dpkg -i cherrytree_0.30.5-1_all.deb
$ sudo apt-get install -f
