live-build fails to build

[thelinuxbox]

Hello, I'm trying to build an Ubuntu ISO with the minimal amount of packages using live-build, towards the end of the building process it says "Unable to locate package syslinux-themes-ubuntu-oneiric" and then it appears to stop the build process, below is the command from my bash file, thank you in advance to any replies.

#!/bin/sh

sudo lb clean

sudo lb config \
--mode ubuntu \
--architecture amd64 \
--distribution xenial \
--archive-areas "main universe multiverse" \
--parent-distribution xenial \
--parent-archive-areas "main universe multiverse" \
--apt-options "--yes" \
--binary-images iso-hybrid \

sudo lb build

1) OS:Ubuntu 16.04.3 LTS
2) Live-Build Version: 3.0~a57-1ubuntu25.5
3) Live-Build to build an installable minimal Ubuntu ISO
4) "Unable to locate package syslinux-themes-ubuntu-oneiric"

Hi, quick update, I tried live-build on debian and it worked without any issues, so it seems to me that the ubuntu build is definitely broken.

Status changed to 'Confirmed' because the bug affects multiple users.

Thank you for your bug report.

Indeed it's obvious from the code was is wrong and should be trivial to fix

functions/defaults.sh has that code

' ubuntu)
   LB_SYSLINUX_THEME="${LB_SYSLINUX_THEME:-ubuntu-oneiric}"
   ;;'

Or the -oneiric binary got removed in xenial so it's probably a matter for doing s/oneiric/xenial there

Tagging rls for foundations review they know better the image build tools and what modes are supposed in Ubuntu

Thank you very much for replying to my bug report, I really appreciate it.

I was just thinking about the live-build tool this morning and was pleasantly surprised to see an email in my inbox with your message.

As soon as an update is available I'd gladly test it out.

Many thanks!

Foundations does not support live-build directly as a tool for building images, but only as an implementation detail of builds driven by livecd-rootfs and ubuntu-cdimage.

Thank you for your reply Steve,

I'd like to ask what solution you'd recommend for building a custom Ubuntu derivative from the command line.

Thank you.

It seems ubuntu-defaults-image from ubuntu-defaults-builder package was a recommended tool for building custom Ubuntu derivative, but this tools is not updated since 2017 :(, see

[Regolith Linux (regolith-linux)]

As of late 2020, there are updates to ubuntu-defaults-builder (FYI).

[Mantas Kriaučiūnas (mantas)]

@ regolith-linux
Please tell me where I can find latest updates to ubuntu-defaults-builder, because I don't see any commits at https://code.launchpad.net/ubuntu/+source/ubuntu-defaults-builder since 2017 :(

Also critical bug #1699925 still isn't fixed :(

It seems ubuntu-defaults-builder is abandoned, maybe better is to use Cubic?
