Thank you for taking the time to report this bug and helping to make
Ubuntu better.
> `apt-get install -y -qq ansible`
This does not guarantee a non-interactive run. If you want a non-
interactive run, you must use all the necessary parameters. For example:
UCF_FORCE_CONFOLD=1 DEBIAN_FRONTEND=noninteractive apt-get -o
Dpkg::Options::="--force-confdef" -o Dpkg::Options::="--force-confold"
-qq -y install ansible
See the dpkg and ucf documentation to set the default behaviour as you
actually want it.
Perhaps this could be better documented in apt-get(8). The -y option
there refers to apt-get itself only and does not apply to underlying
dpkg behaviour and debconf and ucf calls that might be called from
maintainer scripts that need to interact with the user.
Unfortunately my example above isn't a complete answer either, since
there is no unified "must run non-interactively" directive that
individual package maintainer scripts must follow. In general though
they tend to use dpkg's built-in handling, debconf and ucf when
prompting the user is required, so this should cover most (99%+?) cases.
It's valid to say that we could do with a better unified way of
achieving non-interactivity. However, in today's current design, if
you're not calling apt-get with the appropriate parameters as in my
example above, then it's your script that isn't correctly calling for
non-interactivity. All configuration management tooling that expects
non-interactivity needs to be doing this, and this isn't a workaround -
it's the official CLI interface.
Bug 1747464 is related, though that relates to the default conffile
state in our cloud images, so is a more specific instance of the problem
where _interactive_ use causes unnecessary prompts.
This bug is not valid for openssl, because it isn't a bug for it to
prompt in itself. It is perhaps valid for ansible if ansible itself
incorrectly assumes non-interactivity without requesting it correctly -
I don't if that's the case specifically with Ubuntu's ansible package;
if it is, please describe the detail and change that bug status back to
New.
It would be a valid feature request for Ubuntu to request a more unified
way of requesting non-interactivity, though that would be a major effort
as it would require changes across the stack, and wouldn't be of
particularly high priority as we have a good enough (if non-obvious) way
of achieving the same thing today (my example above). Specific requests
to make this clear in documentation would also be valid. Please file
separate bugs for those if you wish. I hope though that I've described
adequately above why the behaviour you describe isn't itself a bug in
the base packages.
** Changed in: openssl (Ubuntu)
Status: New => Invalid
** Changed in: ansible (Ubuntu)
Status: Confirmed => Incomplete
