Linux-Sublime Text install(How you I install Sublime Text 2/3?)

There are 2 Sublime Text PPAs and both install the correct version. You've probably used the Sublime Text 3 PPA but posted the instructions for Sublime Text 2 in your question. I just tried the Sublime Text 2 PPA and it correctly installs Sublime Text 2 and Text :

1. For Sublime-Text-2:

2. sudo add-apt-repository ppa:webupd8team/sublime-text-2
   sudo apt-get update
   sudo apt-get install sublime-text

3. For Sublime-Text-3:
   

4. sudo add-apt-repository ppa:webupd8team/sublime-text-2
   sudo apt-get update
   sudo apt-get install sublime-text
