How to install Aegisub subtitles editor in LinuxLite

Aegisub subtitle editor is very powerful and famous subtitle editr not only among Windows user, but also among Linux users. Unfortunately, Aegisub application is not included in standard repository, so we have to add another repository to get this app. We know, that LiteLinux is using the same repositories like Ubuntu Linux does, so you can easily do it using add-apt-repository command in your terminal:

$ sudo add-apt-repository ppa:alex-p/aegisub

My output was following:

  Originally created as tool to make typesetting, particularly in anime
 fansubs, a less painful experience, Aegisub has grown into a fully fledged,
 highly customizable subtitle editor.
 
 It features a lot of convenient tools to help you with timing, typesetting,
 editing and translating subtitles, as well as a powerful scripting
 environment called Automation (originally mostly intended for creating
 karaoke effects, Automation can now be used much else, including creating
 macros and various other convenient tools).
