All,
I'd reiterate Murray's comments about PHP7.The transition isn't seamless
and you're unlikely to get all the packages you need in the default setup.
I managed to get my sites up relatively quickly, but a lot of the
functionality needed extra packages. Do your homework or some testing
before the switch!
I didn't have any of Murray's issues with getting booted and services
started, luckily.
Cheers,
Andy

Just some quick feedback on the do-release-update to
Ubuntu 16.04.1.
I thought my install of 14.04 was pretty standard, and it turns out I was
wrong. Nothing went so bad that I had to nuke it from orbit, but it's been
a couple of hours of repair work spread over a couple of days.
Firstly, immediately after the update (and restart) systemd hosed pid 1 so
the server wouldn't easily restart - I began to suspect something was up
when systemctl wasn't controlling services, but service <blah> restart (et
al) was still working so things didn't twig immediately. This only really
came to light when I tried to restart the server after restoring everything
else (see below) and that wasn't having it. Google came to the rescue,
there's a way to forcibly reboot using systemctl even when pid 1 is hosed,
and what was basically restart #2 got things happy again.
Not everything PHP 5 was automatically upgraded to PHP 7.0 (didn't have
that much extra over -common, but enough that my website was down for 15
minutes or so). I had been tracking Nginx HEAD via their PPA, so it was a
(very) minor downgrade to track the Ubuntu version (to avoid future
problems, hopefully). The fly in the ointment turned out to be mysql; I had
been using percona 5.6 (via PPA), but knew I wanted to track "stock" 5.7
(which the do--update did for me), but it zapped the config back to
defaults, causing me two days to wondering why Codeguard couldn't back up
my database - turns out that the default config only listens on 127.0.0.1
now... You learn as you go in my world.
Otherwise, a nice enough experience, and I'm loving the speed of PHP 7.0.
Kind regards
Murray Crane
