Public bug reported:
First of all I am not sure that is about a bug or misunderstanding of a
concept.
I am trying to make a custom ISO w/ autoinstall to automatically install Ubuntu
Server 24.04.1 LTS onto our machines. We of course need to install some extra
apt packages as part of the customization. The problem is, this installation
needs to be done entirely offline (mostly with rj45 unplugged), so I can't just
add them to the apt package list and have subiquity magic take care of
everything. Briefly:
- Extract iso. I'll call the extracted dir 'iso';
- Add the packages to iso/pool/universe/path/to/package.deb; added also deps
(apt-get --print-uris --yes install "$package" | grep ^\' | cut -d\' -f2);
- Then to add them to the Packages and Packages.gz file that lists all the
available packages by calling;
- Update the the Release file;
- Create a gpg key and sign the Release file;
- Add the public key (gpg) to trusted keys in
ubuntu-server-minimal.ubuntu-server.squashfs.
- resumm md5 (cd image && find . -type f -print0 | xargs -0 md5sum | grep -v
"\./md5sum.txt" > md5sum.txt)
For testing purpose I downloaded traceroute. user-data looks like:
#cloud-config
autoinstall:
version: 1
source:
id: ubuntu-server
shutdown: poweroff
packages:
- traceroute
identity:
realname: 'UntouchedWagons'
username: ubuntu
password: 'secret'
hostname: local-host
locale: en_US.UTF-8
keyboard:
layout: us
timezone: "Europe/Athena"
storage:
layout:
name: lvm
sizing-policy: all
ssh:
allow-pw: true
install-server: true
authorized-keys:
- some-keys
I've also tried variations and combinations of the above where I've also
specified a "late-commands:" or "network:" section, detailed late. It
"appears" to me that subiquity crash while downloading/install

I searched for "has_network" in
var/crash/1725992736.960986614.install_fail.crash and here are the results:
2024-09-10 18:22:47,079 DEBUG subiquitycore.models.network:469 has_network
False
... also as I was expecting
When the installer crash's while still in the Live session, if I pop into the
terminal and check the following:
apt-get install --download-only traceroute
- works fine
apt-get install traceroute
- works fine
I have used such a method to install our systems since ubuntu 12.04 with seed
files and "d-i pkgsel/include string " worked like a charm. After a lot a
research I found that somehow this is normal behavior:
cat /cdrom/etc/apt/sources.list
"deb cdrom:[Ubuntu-Server 24.04.1 LTS _Noble Numbat_ - Release amd64
(20240827)]/ noble main restricted universe"
and corecly read components from "/cdrom/dists/noble/Release" -> "Components:
main restricted universe"
But in chrooted env that install run:
cat /target/cdrom/etc/apt/sources.list
"deb [check-date=no] file:///cdrom noble main restricted"
the "universe" component is missing because apt.py:L245 says:
write_file(
self.install_tree.p('etc/apt/sources.list'),
f'deb [check-date=no] file:///cdrom {codename} main restricted\n')
that looks laike a fail-safe method
*) what if I need also multiverse?
I have some workarounds for my issue like copying all my debs in a tmp
/target directory and run "dpkg -i *", also copying in
"/target/var/cache/apt/archives" but not sure if it is enought for apt-
get to install it, or even more go to debian. Anyway, none of those
looks for me an elegant one.
My question is that if am I doing something wrong because
autoinstall/subiquity/curtin was designed for different purpose, or
there is any solution?
