yes there is a file /etc/passwd.lock if I remove and try what you said

tapas at ubuntu:/etc$ sudo dpkg -configure -a
dpkg: error: unknown option -o

Well I am not clear with this message of yours.Based on the above
error message I notice
a file
tapas at ubuntu:/etc$ ls shadow
shadow       shadow-      shadow.lock

I removed this also now I did
 sudo dpkg --configure -a
Setting up libvirt-bin (0.9.2-4ubuntu15) ...
here I did not got any error.
Thanks for your suggestions.
I am able to get virt-manager running now.
