***Andy Matuschak (andymatuschak)** [reported (on Launchpad)](https://bugs.launchpad.net/sparkle/+bug/228475) on' 2008-05-09:*

1. Try to update an app without write access.
2. Get authentication prompt; cancel.
3. Check for updates again and authorize this time.
4. Note that Sparkle fails to copy the new app in place but still trashes the old one.
