I am installing packages on remote server, using ssh
:
ssh root@my-host "DEBIAN_FRONTEND=noninteractive DEBCONF_NONINTERACTIVE_SEEN=true apt-get --quiet --yes install w3m"
even though I have set DEBIAN_FRONTEND=noninteractive
, the installation gets stuck on following question, and I have to press enter manually:
Configuration file '/etc/w3m/config'
==> File on system created by you or by a script.
==> File also in package provided by package maintainer.
What would you like to do about it ? Your options are:
Y or I : install the package maintainer's version
N or O : keep your currently-installed version
D : show the differences between the versions
Z : start a shell to examine the situation
The default action is to keep your current version.
*** config (Y/I/N/O/D/Z) [default=N] ?
I suspect, the question is being asked by dpkg --configure -a
and not by apt-get
and therefore noninteractive is ignored.
How can I automate this and have default option selected automatically, without being asked ?

This is dealt with by
dpkg
, and you can force it to choose the default option using the--force-confdef
option. Do heed the warning from the documentation though:To provide this option when
dpkg
is invoked by APT, you need to add it to the APT settings, for example by adding the following line to/etc/apt/apt.conf
:or, for a single invocation:
