Hi David,
there are a few things in your log that could be related.
First of all - the server has to be restarted on upgrade to pick up th enew code, that restart seems to fail.
But also there is an issue in postinst trying to enable all modules you had.

From the log (1):
info: Executing deferred 'a2enconf javascript-common' for package javascript-common
ERROR: Conf javascript-common does not exist!
dpkg: error processing package apache2 (--configure):
 subprocess installed post-installation script returned error exit status 1

Please check if you have "javascript-common" installed.
If you do so please check a2enconf manually and why it might fail.

From the log (2):

The times there are odd, maybe you fixed this already between 15:36 and 16:42?
But from what I found in the net about that it might be an issue in the http config.
If you have modified that you might consider saving your custom config, restart with the one Ubuntu provides [1] and then step by step reenable your changes until you find what broke it.

Thank you for taking the time to report this bug and helping to make Ubuntu better.

Since it seems likely to me that this is a local configuration problem, rather than a bug in Ubuntu, I'm marking this bug as Incomplete for now.

If indeed this is a local configuration problem, you can find pointers to get help for this sort of problem here: http://www.ubuntu.com/support/community

Or if you believe that this is really a bug, then you may find it helpful to read "How to report bugs effectively" http://www.chiark.greenend.org.uk/~sgtatham/bugs.html. We'd be grateful if you would then provide a more complete description of the problem, explain why you believe this is a bug in Ubuntu rather than a problem specific to your system, and then change the bug status back to New.

Many thanks for your swift and detailed reply, Christian.

I resolved it with a purge remove and a fresh install Orherwise, my
upgrade fron 14.04 to 16.04 was issue free.

Best Wishes
