Same here. Kodi closes after download has finished and nothing more happens.

 *Workaround till its fixed*

open you favorite file explorer, I use Total Commander and navigate to:

xml:
/storage/emulated/0/Android/data/org.xbmc.kodi/files/.kodi/userdata/addon_data/script.kodi.android.update

from there you can run the update apk.   

This will only work after you disabling "Cleanup" in settings. Otherwise, the script will delete the apk after Kodi reboots.  

 No, this will happen after kodi is updated. 

So you start kodi installer, kodi is downloaded, kodi will crash, you install the update manually, the update will deleted on first start.
