Problem: Try to install an addon where it fails to download. The progress will go to 0% and then vanish, without any error popups or interaction of any kind. If the user has installed other addons he may guess that it failed, if this is his first addon he may very well think it was installed.

Solution: A first and simple solution is a popup stating that addon X failed to download. Another solution would be to reschedule a download later and useing label2 (where the progress is) say "failed to download, retrying in (x)"

from jm:

The way we handle add-on installation needs a complete rethink IMO. Resolving dependencies before install, installing dependencies fifrst, issues with dependencies disappearing and so on all need rethinking through. Further, we need to better consider how we handle rolling back to earlier versions of XBMC (Frodo->Eden for example) where Frodo add-ons are left behind yet are still started by Eden.
