Solution 1

You need to pass some dpkg options to your commands, for instance:

export DEBIAN_FRONTEND=noninteractive
apt-get update && 
    apt-get -o Dpkg::Options::="--force-confold" upgrade -q -y --force-yes &&
    apt-get -o Dpkg::Options::="--force-confold" dist-upgrade -q -y --force-yes

On a side note, I would recommend using only dist-upgrade, you will eventually end up with broken dependencies if you use upgrade.

Solution 2

>= Apt 1.1

If you're using Apt 1.1 or above, --force-yes has been deprecated, so you've to use the options starting with --allow instead, e.g. --allow-downgrades, --allow-remove-essential, --allow-change-held-packages.

So the command is:

DEBIAN_FRONTEND=noninteractive \
  apt-get \
  -o Dpkg::Options::=--force-confold \
  -o Dpkg::Options::=--force-confdef \
  -y --allow-downgrades --allow-remove-essential --allow-change-held-packages

^{Note: Use --force-confold to keep old, and --force-confnew to keep new configs.}

I'm trying to make an update fully non interactive.(on ubuntu 14.04.3 LTS) I thought it will be easy with this type of command:

export DEBIAN_FRONTEND=noninteractive
apt-get update && apt-get upgrade -q -y --force-yes && apt-get dist-upgrade -q -y --force-yes

but no... I always have a question like:

Configuration file '/etc/cloud/cloud.cfg'
 ==> 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.
*** cloud.cfg (Y/I/N/O/D/Z) [default=N] ?

So do you known how I can accept the default value automatically ?

For any other fellow travelers that find this, the quoting around Dpkg::Options is wrong. it should be: apt-get -o "Dpkg::Options::=--force-confold" dist-upgrade -y --force-yes

For use within sudo, make sure to put the environment variable in front of the command rather than hoping sudo won't strip your envs, like: sudo DEBIAN_FRONTEND=noninteractive apt-get -o "Dpkg::Options::=--force-confold" dist-upgrade -y --force-yes

@Irving, that quoting worked for me, perhaps something changed recently?

W: --force-yes is deprecated, use one of the options starting with --allow instead. (apt v1.1 and newer). Looks like the new equivalent is --allow-downgrades --allow-remove-essential --allow-change-held-packages

I think you're missing the word "update" in your command someplace?
