Bug#1030232: apt-get install -y should use noninteractive debconf frontend
Package: apt
Version: 2.4.8
Severity: minor
X-Debbugs-Cc: debbugs@kalvdans.no-ip.org
Dear Maintainer,
When I install a package with the -y flag, according to the man page should give me a noninteractive mode. However, it still uses the Dialog frontend. See the following output:
root@8a97f9bba510:/# apt-get install -y exim4

debconf: unable to initialize frontend: Dialog
debconf: (No usable dialog-like program is installed, so the dialog based frontend cannot be used. at /usr/share/perl5/Debconf/FrontEnd/Dialog.pm line 78.)

A workaround is to run "DEBIAN_FRONTEND=noninteractive apt-get install exim4" instead.
Reported from Ubuntu 22.04 but the Debian package is affected as well.
