Bug#1037004: msmtp-mta doesn't respect DEBIAN_FRONTEND=noninteractive

[Greg]

Package: msmtp-mta
Version: 1.8.6-1
Severity: important

Dear Maintainer,

Regarding your commit here: https://salsa.debian.org/kolter/msmtp/-/commit/7633ea472e24bf3be003396a2e4567d101f8cf53

This has added a TUI when installing the `msmtp-mta` package that appears even on non-interactive terminals. This is making it very difficult for us to upgrade our Gitlab install which has this command in a Dockerfile:

RUN DEBIAN_FRONTEND=noninteractive apt-get -y update && \
apt-get install -yq --no-install-recommends msmtp-mta s-nail htop dialog less paxctl sudo

The command is executed by `docker-compose build --pull`

However the TUI shows up and there’s no way to dismiss it without aborting the install. Pressing enter/space etc does not work, it only types keys over the TUI.

Any help with this is greatly appreciated!

Before installing or upgrading msmtp-mta (or msmtp) from your Dockerfile
try to pressed the debconf questions by executing the following
commands:

echo "msmtp msmtp/apparmor boolean false" | debconf-set-selections
echo "msmtp msmtp/security-information error seen" | debconf-set-selections

Let me know if it works.

Have a nice day.

I didn't noticed it in the first place but you also have to set the
noninteractive frontend when installing/updating the package not only
when updating the packages index.

Try:
RUN DEBIAN_FRONTEND=noninteractive apt-get -y update && DEBIAN_FRONTEND=noninteractive apt-get install -yq --no-install-recommends msmtp-mta s-nail htop dialog less paxctl sudo

If it works as expected it's far better than preseeding (suggested in my
previous reply).

Wow, that worked! Sorry for not understanding that that had to be prepended to both commands.

Lesson learned! Thank you and please feel free to close this bug report now (I have no idea how to do that).
