How to do *dpkg-reconfigure dash* as bash automatically
Pasting Daniel's comment as an answer here since it doesn't rely on default settings from dpkg-reconfigure
.
To get options:
debconf-show dash
To set this particular option to false
:
echo "dash dash/sh boolean false" | debconf-set-selections
and to actually reconfigure the package:
DEBIAN_FRONTEND=noninteractive dpkg-reconfigure dash
This worked for me from a Dockerfile:
# make /bin/sh symlink to bash instead of dash:
RUN echo "dash dash/sh boolean false" | debconf-set-selections
RUN DEBIAN_FRONTEND=noninteractive dpkg-reconfigure dash
You can make debconf only ask for high or critical questions[1].
Ex:
dpkg-reconfigure -p critical dash
dpkg-reconfigure will use default answer defined in debconf script. You can also use debconf-get-selections to pick up different answer for noninteractive installation[2].
