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.
