sudo dpkg --configure -a not resolving blocking of synaptic & updating

[m654321]

Synaptic Package Manager wouldn't open fully in LL3.0 today, but came up with message to run this command: sudo dpkg --configure -a.
I assume this happened because a process was abruptly terminated in a previous session, before it had reached completion.
I got the following output when I ran the command mentioned, but it seems to hang indefinitely (more than an hour) on the last line of code... 

Code:

mike@mike-G750JS:~$ sudo dpkg --configure -a
[sudo] password for mike:
Setting up linux-image-4.4.0-42-generic (4.4.0-42.62) ...

As always, any help is much appreciated.
