I'm trying to provision a machine using Vagrant and plain bash scripts.
The two lines are:
DEBIAN_FRONTEND=noninteractive apt-get update
DEBIAN_FRONTEND=noninteractive apt-get upgrade -yqHowever, it doesn't work as expected:
default: Configuration file '/etc/update-manager/release-upgrades'
default: ==> Modified (by you or by a script) since installation.
default: ==> Package distributor has shipped an updated version.
default: What would you like to do about it ? Your options are:
default: Y or I : install the package maintainer's version
default: N or O : keep your currently-installed version
default: D : show the differences between the versions
default: Z : start a shell to examine the situation
default: The default action is to keep your current version.
default:
default: *** release-upgrades (Y/I/N/O/D/Z) [default=N] ? dpkg: error processing package ubuntu-release-upgrader-core (--configure):
default:
default: end of file on stdin at conffile promptIs there any other option I could use to provide a Y answer to that?

< Apt 1.1
Try the following command to force upgrade for non-interactive sessions:
DEBIAN_FRONTEND=noninteractive \ apt-get \ -o Dpkg::Options::="--force-confnew" \ --force-yes \ -fuy \ dist-upgradeNote: Use --force-confold to keep old, and --force-confnew to keep new configs.
Source: apt-get -y upgrade for non-interactive sessions - and replacing conf files in /etc.
>= 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-packagesSource: CFE-2360: Make apt_get package module version aware.
