It is possible to install kodi on raspberry pi 2 ?
The top line on http://kodi.wiki/view/Raspberry_Pi should answer your question.
Always remember… Google is your friend! 
OSMC runs Kodi. If you are talking about getting the ‘classic’ look back: see

I tried OSMC RC with Confluence.
For some reason the movie-scraper did not work (could not connect to server). It was not possible to find add-ons (the list in “get-more” add-ons in video and software was empty).
The tv- and music-scrapers did work and I could update osmc.
Everything works fine with my old raspbmc on raspberry pi B+ i.e. network is okay.
I am now testing a fresh install with openelec on my new raspberry pi 2 which seems to work “out-of-the-box” (thus eliminating hardware-problems). Later I will retry osmc.
