python - 如何处理使用 python-apt 生成多个配置对话框屏幕的 apt 安装？

Question

例如，当安装 lirc 包时，它会提供配置对话框屏幕。如何自动化以选择默认值(或可能提供特定值)并继续？

现在我有一个简单的脚本:

  #!/usr/bin/env python
  import apt
  import sys

  pkg_name = "lirc"

  cache = apt.cache.Cache()
  cache.update()

  pkg = cache[pkg_name]
  if pkg.is_installed:
      print "{pkg_name} already installed".format(pkg_name=pkg_name)
  else:
      pkg.mark_install()

      try:
          cache.commit()
      except Exception, arg:
          print >> sys.stderr, "Sorry, package installation failed [{err}]".format(err=str(arg))

Answer 1

你可以使用

export DEBIAN_FRONTEND=noninteractive

然后使用 debconf提供您选择的值。这howto解释

If you want to supply an answer to a configuration question but do not want to be prompted for it then this can be arranged by preseeding the DebConf database with the required information. You will need to know:

• the name of the package responsible for asking the question (which might not be the one you asked to install if there are dependencies),
• the configuration database key against which the answer is recorded, and
• the type of the answer (string, boolean, select, multiselect or password).

也可以在 python-apt 中使用 apt_pkg.Configuration 提供配置选项类(class)。举例说明

apt_pkg.config.set("Dir", self.tmpdir)

然后您必须找到配置脚本要求的选项的名称，并通过 python 脚本设置它。
