apt-get upgrade -y not completing

[virtualjj]

When using apt-get upgrade -y or apt-get dist-upgrade -y Userdata fails and does not complete because the following messages are requiring interactive input:

Configuration file '/etc/issue'
  ==> Modified (by you or by a script) since installation.
  ==> Package distributor has shipped an updated version.
   What would you like to do about it ?  Your options are:
   Y or I  : install the package maintainer's version
   N or O  : keep your currently-installed version
   D     : show the differences between the versions
   Z     : start a shell to examine the situation
The default action is to keep your current version.
 *** issue (Y/I/N/O/D/Z) [default=N]

Configuration file '/etc/cloud/cloud.cfg'
  ==> Modified (by you or by a script) since installation.

Have tried the following commands within Userdata using advice from Stackoverflow but the result is the same:

DEBIAN_FRONTEND=noninteractive apt-get -y -o Dpkg::Options::="--force-confdef" -o Dpkg::Options::="--force-confnew" upgrade

export DEBIAN_FRONTEND=noninteractive
apt-get -o Dpkg::Options::="--force-confnew" upgrade -y 

export DEBIAN_FRONTEND=noninteractive
apt-get -q -y upgrade

For now have not included apt-get upgrade -y in the Userdata script.

This issue is gone with the new OpenVPN AMIs.
