Ok. Ian, Sri, could you also both check whether running efibootmgr on Ubuntu 19.10 succeeds? Probably the easiest check is a no-op rewrite of the boot order variable. Ian, for you the command would be:

sudo efibootmgr -o 0000,3000,0001,0002,2001,2002,2003; echo $?

Sri, for you the command would be:

sudo efibootmgr -o 0000,0003,0004,0001; echo $?

Please post the complete output of this command.

This will help us determine whether there is a bug in the grub implementation of variable writing, or if there's a bug in the underlying libraries used by both grub and efibootmgr.
