Public bug reported: I have used Ask Ubuntu with a description of the problem https://askubuntu.com/questions/1513034/problems-installing-24-04/1513141#1513141
I have a manual partition in order to keep separate the "/" from "/home" and to overwrite the Ubuntu while not touching the user data. The upgrade to 24.04 is failing and I think the reason is that it can't find the grub on the iso file.
