The Xubuntu install was an install into one partition (SDA2) where two partitions exist both with OSes (SDA1 & SDA2).
The resulting Xubuntu install booted without grub appearing on boot, and no way for a user to boot into prior SDA1 install of Lubuntu noble.
Attempt as in original post of `sudo update-grub` reports
Warning: os-prober will not be executed to detect other bootable partitions.
thus my prior 24.04 system is not offered as boot option.
I've NOT encountered this issue with an auto(resize)/install-alongside install, ONLY with something-else/manual-partitioning type of installs.. so its not all installs.
