[Bug 2086843] Re: Grub creates spurious entries in the menu

[corrado venturini]

I don't know if this is related to the problem, but I see that Jammy's os-prober doesn't see Ubuntu installs after version 24.04.
Below is the call to os-prober on Jammy and Plucky on the same PC.
The partitions with Ubuntu 24.10 and 25.04 and the one with Debian trixie/sid are ignored by os-prober 1.79ubuntu2 

corrado at corrado-b2-jammy:~$ apt policy os-prober
