no, a `find /boot/efi` would have shown (i added the ubuntu 
here manually, but that's how it was if i remember correctly):

/boot/efi/EFI/Boot

when i issue a `efibootmgr` it shows the list of efi variables 
(here i again added the ubuntu entry manually as i remember 
it):

BootCurrent: 0001
Timeout: 1 seconds
BootOrder: 0001,0002,0003,0004,0005,0006
Boot0000  Windows Boot Manager	HD(1,GPT,...
Boot0001* debian	HD(1,GPT,...
Boot0002* ubuntu	HD(1,GPT,...
Boot0003* Windows Boot Manager	HD(1,GPT,...
Boot0004* UEFI:CD/DVD Drive	BBS(129,,0x0)
Boot0005* UEFI:Removable Device	BBS(130,,0x0)
Boot0006* UEFI:Network Device	BBS(131,,0x0)

as far as i understand the system uses BootOrder to determin 
what to boot. it starts with 0001 which is debian, not 
ubuntu. so i wonder why the leftover ubuntu grub was booted as 
you say (which i believe, i am not an efi expert).

that the system wont be able to boot into debian.

maybe it could change BootOrder to point to the debian entry 
only?
