(note found this later this does not work the error was still there) So I first ran the command

sudo fuser -v /var/cache/debconf/config.dat

and I got this

/var/cache/debconf/config.dat:
USER        PID ACCESS COMMAND
root      40970 F.... frontend

and so i got the process id (40970) and killed it sudo kill 40970 (insert the process id).

Then I did sudo apt upgrade

and then I got this

Configuring grub-efi-amd64 GRUB failed to install to the following devices: /dev/sda2  
Do you want to continue anyway?  
If you do, your computer may not start up properly.  
Writing GRUB to boot device failed - continue? <Yes> <No>

So I pressed <No>, then <Ok> and I think it's fixed.
