Please see the image below, is there a preseed directive to skip this Debian9 installer step?

Currently I use the following config relevant to the package manager:

### Apt setup
d-i apt-setup/non-free boolean true
d-i apt-setup/contrib boolean true
d-i apt-setup/local0/source boolean true

### Package selection
tasksel tasksel/first multiselect standard

### Mirror settings
d-i mirror/country string manual
d-i mirror/http/hostname string httpredir.debian.org
d-i mirror/http/directory string /debian
d-i mirror/http/proxy string

Debian9 Installer

  • From the top of my head, you have to add a debian repository for it to be used. Dec 6, 2017 at 13:36
  • @RuiFRibeiro Please see edited question, I indeed use a mirror.

  • would you please add to question how are you making the security update? Dec 6, 2017 at 13:46
  • security.debian.org is added to the sources.list regardless the mirror I choose. Hopefully this answers your question.

For it not to scan your DVD/netinst image, add these directives to your preseeding configuration:

d-i apt-setup/cdrom/set-first boolean false
d-i apt-setup/cdrom/set-next boolean false   
d-i apt-setup/cdrom/set-failed boolean false
