debconf-set-selections - Online in the Cloud

Run debconf-set-selections in OnWorks free hosting provider over Ubuntu Online, Fedora Online, Windows online emulator or MAC OS online emulator

This is the command debconf-set-selections that can be run in the OnWorks free hosting provider using one of our multiple free online workstations such as Ubuntu Online, Fedora Online, Windows online emulator or MAC OS online emulator

PROGRAM:

NAME


debconf-set-selections - insert new values into the debconf database

SYNOPSIS


debconf-set-selections file
debconf-get-selections | ssh newhost debconf-set-selections

DESCRIPTION


debconf-set-selections can be used to pre-seed the debconf database with answers, or to
change answers in the database. Each question will be marked as seen to prevent debconf
from asking the question interactively.

Reads from a file if a filename is given, otherwise from stdin.

WARNING


Only use this command to seed debconf values for packages that will be or are installed.
Otherwise you can end up with values in the database for uninstalled packages that will
not go away, or with worse problems involving shared values. It is recommended that this
only be used to seed the database if the originating machine has an identical install.

DATA FORMAT


The data is a series of lines. Lines beginning with a # character are comments. Blank
lines are ignored. All other lines set the value of one question, and should contain four
values, each separated by one character of whitespace. The first value is the name of the
package that owns the question. The second is the name of the question, the third value is
the type of this question, and the fourth value (through the end of the line) is the value
to use for the answer of the question.

Alternatively, the third value can be "seen"; then the preseed line only controls whether
the question is marked as seen in debconf's database. Note that preseeding a question's
value defaults to marking that question as seen, so to override the default value without
marking a question seen, you need two lines.

Lines can be continued to the next line by ending them with a "\" character.

EXAMPLES


# Force debconf priority to critical.
debconf debconf/priority select critical

# Override default frontend to readline, but allow user to select.
debconf debconf/frontend select readline
debconf debconf/frontend seen false

OPTIONS
