I would like to know if and how it is possible to do a non-interactive
install of an .deb package. The pages I have read talk only of a 'yes to
all questions' option which is obviously useless if the package you are
installing has questions other than yes/no and so on.
The docs also speak of being able to set *arbitrary* options in the
command
line. This seemed to be more related to the apt-get program rather than
the
packages.
Two examples I want to do are Apache2 and PostgreSQL which require some
additional prompting. The purpose here is to create a set of steps which
can quickly install a Debian system from scratch, limit down-time and
remove
some of the human element.
Is there a way of doing this? I'm at about a 3 bananas out of 5 on the
howler monkey scale.
How about debconf pre-seeding? Most programs use debconf to ask the
questions. However if debconf already
has answers to the questions then it does not bother to ask them. In fact
the config script is apparently sometimes
run in both the pre-inst and the postinst so ignoring questions which have
answers already is almost critcal.
The following is one way to pre-seed debconf. With this method it is very
important that you not pre-seed for any
packages that will not be installed, because otherwise those values will rot
in the database forever.
Anyway lets say the package name is 'foobar'
From a system where it is already configured you should run:
debconf-get-selections|grep ^foobar > foobar.preseed
Then to load that into the database to avoid the questions, simply get the
file onto the system and run:
debconf-get-selections foobar.preseed
Note thatyou can concatonate a bunch of these file together if you want.
This will then let you use only one line to
pre-seed a whole bunch of packages.
There are also other ways to pre-seed, but I don't know about them.
