how to install Devstack on Ubuntu 16.04 Server

Question

As I made for the previously release of DevStack, for install it I've always run the same steps:

1 - Create a Stack user:

$: sudo groupadd stack
$: sudo useradd -g stack -s /bin/bash -d /opt/stack -m stack
$: sudo passwd stack
$: sudo visudo

then add line

stack ALL=(ALL) NOPASSWD:ALL

save the file and exit, logout and login as that user.

2 - Download the pack:

$: git clone https://git.openstack.org/openstack-dev/devstack -b stable/mitaka

3 - Create a local.conf

using this guide, https://gist.github.com/amotoki/b5ca4affd768177ed911

$: nano local.conf

4 - Install Devstack

$: ./stack

but I get an error like this:

[ERROR] ./stack.sh:191 If you wish to run this script anyway run with FORCE=yes
/home/richardsith/devstack/functions-common: line 232: /opt/stack/logs/error.log: No such file or directory

the line 191 says:

# Warn users who aren't on an explicitly supported distro, but allow them to
# override check and attempt installation with ``FORCE=yes ./stack``
if [[ ! ${DISTRO} =~ (trusty|vivid|wily|7.0|wheezy|sid|testing|jessie|f22|f23|rhel7|kvmibm1) ]]; then
    echo "WARNING: this script has not been tested on $DISTRO"
    if [[ "$FORCE" != "yes" ]]; then
        die $LINENO "If you wish to run this script anyway run with FORCE=yes"
    fi
fi

this task was passed using the command:

$: FORCE=yes ./stack

but during the procedure I receive this error:

2016-06-07 13:47:09.480 | +./stack.sh:exit_trap:498                  exit 1

also this step has been resolved run the command where the installer was stopped, in this case

$: sudo cp -p /opt/stack/keystone/etc/policy.json /etc/keystone
$: FORCE=yes ./stack

same step for all the error received during the installation.....

Why if I set the Stack user with sudo privileges receive the error of permission denied? thanks in advance

Official guide.
http://docs.openstack.org/developer/devstack/ 
My guide.
apt-get update
cd /
git clone https://git.openstack.org/openstack-dev/devstack
optionally -b stable/juno || stable/liberty || stable/mitaka
cd devstack/
cp samples/local.conf local.conf
vi local.conf
ADMIN_PASSWORD=xxxxxx
MYSQL_PASSWORD=$ADMIN_PASSWORD
RABBIT_PASSWORD=$ADMIN_PASSWORD
SERVICE_PASSWORD=$ADMIN_PASSWORD
/devstack/tools/create-stack-user.sh
chown -R stack:stack /devstack
su stack
/devstack/stack.sh

Don't use root/sudo for ./stack or ./rejoin. It will break your installation

Messing up with permissions like that won't get you anywhere.. If you don't want to use the tested 14.04 lts, perhaps you can use docker, and simply follow the official procedure as described here..
