Thx for pointing me in the right direction, I was able to fix my problem.

It seems my system broke because the install_devices was configured to the 
partition and not the device.

$ lsblk --output NAME,TYPE,SIZE,FSTYPE,MOUNTPOINT,PTTYPE,MODEL
NAME   TYPE   SIZE FSTYPE MOUNTPOINT PTTYPE MODEL
sda    disk 232.9G                   dos    Samsung_SSD_840_EVO_250GB

# Configuration which broke my system with the upgrade from 2.02 to 2.04
$ sudo debconf-show grub-pc|grep install_devices:
* grub-pc/install_devices: /dev/disk/by-id/ata-
Samsung_SSD_840_EVO_250GB_S1DBNSADC65873B-part1

# Configuration which worked when I upgraded from 2.02 to 2.04
$ sudo debconf-show grub-pc|grep install_devices:
* grub-pc/install_devices: /dev/disk/by-id/ata-
Samsung_SSD_840_EVO_250GB_S1DBNSADC65873B

I vaguely remember that one of the grub upgrades (a long time ago) asked me if 
I would like to change the installation location but as far as I remember I 
never changed it.
