Hi all,
does anyone have a working config (preseed.cnf) for bullseye? I'm pulling
my hair out, I tried every possible combination of below mentioned config options to skip apt media scanning...
It seems that d-i apt-setup/cdrom/set-first boolean false is simply
ignored. Possible bug?
Any help would be appreciated.

TL'DR:
The issue:
While using preseed file, regardless of any setting, debian installer
(dialog) jumps off to interactive mode on error: "Apt configuration
problem. An attempt to configure apt to install additional packages from
the media failed". This happens just after installing the base system.
After pressing continue - apt scans mirror correctly and the rest of the process goes unattended till the end.

Preseed file includes (whole file can be here: http://paste.debian.net/1257950/):
<...>
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

apt-cdrom-setup apt-setup/cdrom/set-first boolean false
apt-cdrom-setup apt-setup/cdrom/set-next boolean false
apt-cdrom-setup apt-setup/cdrom/set-double boolean false
apt-cdrom-setup apt-setup/cdrom/set-failed boolean false
<...>

ISO file used for installation: debian-cd/current/amd64/iso-cd/debian-11.5.0-amd64-netinst.iso

Boot command:
auto=true priority=critical preseed/url="" href=" http://ip_address_colon_mark_port/debian-preseed.txt"> http://ip_address_colon_mark_port/debian-preseed.txt

Additionally I uploaded console log screenshot here: https://i.imgur.com/lKtgqyZ.png
and error itself (from d-i): https://imgur.com/eZbMPTy.png

Running installer with DEBCONF_DEBUG=5 do not provide any additional information.

From https://preseed.einval.com/debian-preseed/bullseye/amd64-main-full.txt

it seems that only apt-setup/cdrom/set-failed should be sufficient:

### Description: Scan extra installation media?
# An attempt to configure apt to install additional packages from the
# media failed.
# .
# Please check that the media has been inserted correctly.
# d-i apt-setup/cdrom/set-failed boolean true

Unfortunately this does not work :/

These are processed by the scripts from here:

https://salsa.debian.org/installer-team/apt-setup/-/tree/master/generators/

in particular 41cdset and maybe somthing is going on in 40cdrom.

Those end up in /usr/lib/apt-setup/generators within the running D-I.

You might want to add a `set -x` at the head of each of them to see what
exacly they're up to.

I have some (not recently tested) scripting for doing that here:

https://hands.com/d-i/preseed/classes/dbg/files/HandsOff-dbg-fn.sh

See the function add_x(), the use of which can be seen (commented out)
here:

https://hands.com/d-i/preseed/classes/dbg/files/debug_lvm

That's all rather entangled with this framework:

https://hands.com/d-i

so is not very easy to deploy in that exact form, but you could use
the sed from add_x() combined with a copy of this:

https://hands.com/d-i/bug/820818/

If you replace the mv in kludge.sh with a sed command for the two
generator scripts, and also add the preseed/run setting to your
preseed.cfg, that should do the trick, and fill /var/log/syslog with
debugging output.

HTH

Cheers, Phil.
