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'. root@ub01:~# apt-get upgrade Reading package lists... Done Building dependency tree Reading state information... Done Calculating upgrade...
