Output confirms LL3.4 installed, os-prober command sees it, but update-grub command does not. Ubuntu's grub.cfg file still has old LL2.8 entry.
If memory serves me, LL2.8 is a version that did not play well with others if its grub was not the one in control of booting. (I believe that is no longer the case with newer versions of LL.) So my best guess is that you must have had to manually do something special in Ubuntu to make an entry that would boot LL2.8 and to de-activate the os-prober script from running when performing an update to grub (eg. for new Ubuntu kernels) so that grub updates would not break ability to boot LL2.8.
Boot into Ubuntu and post back with output from this command please:
