Seguridad primero. Hacer copia de seguridad, hacer copia de seguridad, hacer copia de seguridad.
sudo rm /boot/grub/menu.lst
y
sudo rm /etc/kernel/postrm.d/x-grub-legacy-ec2también
sudo rm /boot/grub/default
Entonces prueba sudo dpkg --configure -aNo, ¿error?
sudo apt install --reinstall grub-common grub-gfxpayload-lists grub-pc grub-pc-bin grub2-common
Después de eso, instalamos el código de arranque en el MBR. sudo dpkg-reconfigure grub-pc
Si solo tiene un disco duro, /dev/sda es el lugar correcto.

Los errores que está cometiendo se explican por sí solos:
dpkg-query: error: package 'grub-legacy-ec2' is not installed
Creo que realmente necesitas instalar ese paquete. ¿Intentar hacer eso y volver a intentarlo? sudo apt install grub-legacy-ec2
Respuesta3
En mi caso tuve una ligera variación a lo anterior:
Eliminé /etc/kernel/postinst.d/x-grub-legacy-ec2 además de postrm.d
El kernel 4.15 parece provenir del paquete linux-image-virtual. Lo eliminé, pero el error persistió. Luego edité /boot/grub/menu.lst y eliminé todas las entradas que indicaban la versión 4.15 del kernel (que apuntaban a archivos inexistentes).
