---Problem Description---
apt-get upgrade process is hung when it comes to update the initramfs and it
never finishes with any error messages. So I have to kill the process and
restart it. But the system asks run 'sudo dpkg --configure -a' to correct the
problem if I run 'apt-get upgrade' again. I got the same problem with running
'dpkg --configure -a'.
