Often when updating my Ubuntu systems, I am presented with the following after running apt-get
Generating grub configuration file ... Found linux image: /boot/vmlinuz-3.13.0-77-generic Found initrd image: /boot/initrd.img-3.13.0-77-generic Found memtest86+ image: /memtest86+.elf Found memtest86+ image: /memtest86+.bin done The link /vmlinuz.old is a damaged link Removing symbolic link vmlinuz.old you may need to re-run your boot loader[grub] The link /initrd.img.old is a damaged link Removing symbolic link initrd.img.old you may need to re-run your boot loader[grub]
To re-run your boot loader use the following command.
sudo update-grub
