Hi Moishe,
it seems to hang on enabling php7.1
From your log:
info: Executing deferred 'a2enmod php7.1' for package libapache2-mod-php7.1
ERROR: Module php7.1 does not exist!

I installed the same on a fresh 17.10 system but it worked fine.
From the bit the logs tell me I'd assume something is odd with the config or package content of libapache2-mod-php7.1.

You have to be aware that is you modified a config - just reinstalling will not reset to the defaults - see [1].

You could also verify the status of the package vs it's original state with:
$ dpkg --verify libapache2-mod-php7.1

Also since it fails at enabling it you can
a) check the current status
$ a2query -m php7.1
b) try to enable yourself (after being installed) and see what breaks
$ a2enmod php7.1

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.

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.
