Could you please issue the following commands:
sudo apt-get update
sudo apt-get install grub
sudo dpkg-reconfigure grub
and tell me if the updates work afterwards? Seems some files related to the GRUB configuration got corrupt.

THIS IS THE RESULT :

What about "sudo dpkg-reconfigure grub"? That's the crucial part, since it should try to fix the configuration error you're experiencing.

[manik garg (maneik-deactivatedaccount)]

It did nothing.I issued the command and nothing happened.

[Brian Murray (brian-murray)]

You have too many quotes in this line:

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash i8042.reset""

in your /etc/default/grub file. You want only 1 ending quote not 2.

do-release-upgrade got me this error.
