I did a slight variation: First I started with:

PKG=golang-github-denverdino-aliyungo-dev; mmdebstrap \
--chrooted-customize-hook="set -x ; apt -y install $PKG && sed -e
s/bookworm/trixie/ -i /etc/apt/sources.list && apt update" \
--chrooted-customize-hook=bash bookworm /dev/null

Then I copied the resulting deb files into /tmp/mmdebstrap.*/packages

And added the following to /tmp/mmdebstrap.*/etc/apt/sources.list:

deb [trusted=true] file:///packages ./

Also, inside the chroot I created the necessary index files with:

apt-ftparchive packages . > Packages
apt-ftparchive release . > Release

Then, after an `apt-get update && apt-get dist-upgrade`, I didn't end up
with held back packages:

root@x1:/packages# apt update
Get:1 file:/packages ./ InRelease
Ign:1 file:/packages ./ InRelease
Get:2 file:/packages ./ Release [816 B]
Get:2 file:/packages ./ Release [816 B]

I believe this is a more realistic test than patching the apt internal
files, as I don't
claim to be an expert on apt internals at all

I failed to reproduce this. I did:

gbp clone vcsgit:golang-github-golang-protobuf-1-5
cd golang-github-golang-protobuf-1-5/
dch -i '' -D unstable
git deborig
sbuild
cd ..
mmdebstrap --customize-hook='copy-in \
golang-github-golang-protobuf-1-5-dev_1.5.4-1.1_all.deb \
protoc-gen-go-1-5_1.5.4-1.1_amd64.deb /opt' \
--chrooted-customize-hook="set -x ; apt -y install \
golang-github-denverdino-aliyungo-dev apt-utils && cd /opt && \
apt-ftparchive packages . > Packages && \
apt-ftparchive release . > Release && \
echo 'deb [trusted=true] file:///opt ./' >> /etc/apt/sources.list && \
sed -e s/bookworm/trixie/ -i /etc/apt/sources.list && \
apt update && apt dist-upgrade" bookworm /dev/null

And I still get:

The following packages have been kept back:
golang-github-denverdino-aliyungo-dev

Can you please verify?

Cheers Jochen
