I booted my PC in to kernel version 3.3.8 and everything was fine, no error and I could log on to my session. If of any help this is the output of the dpkg command for installing the kernel, it has no errors unlike the ones that gave me the error: letozaf@letozaf-pc:~/Downloads/kernel/3.3.8$ sudo dpkg -i *.deb [sudo] password for letozaf: Selecting previously unselected package linux-headers-3.3.8-030308.
