Package: mmdebstrap
Version: 1.4.0-1
Severity: normal
Hi. I'm seeing a failure that I understand very well, but yet don't know
how to debug or fix. Any suggestions would be appreciated.
I'm making an Ubuntu/focal image that has a bunch of stuff installed,
and can serve as a base for development. This runs on arm64. There're a
number of ugly external APT repos that have semi-broken packages, but it
should all still work.
I define the stuff I want to install into the image with a meta-package.
tst-libopencv.equivs:
Source: tst-libopencv
Section: misc
Priority: optional
Standards-Version: 3.9.2
Package: tst-libopencv
Version: 1
Maintainer: Dima Kogan <dko...@debian.org>
Depends: ros-noetic-cv-bridge,
libopencv-dev (<< 4.5)
Architecture: arm64
Description: Test
And I build the meta-package:
equivs-build -aarm64 tst-libopencv.equivs
And I can use mmdebstrap to create a base image with this package
installed:
mmdebstrap
\
--verbose
\
--architectures=arm64
\
--hook-dir=/usr/share/mmdebstrap/hooks/file-mirror-automount
\
--include ./tst-libopencv_1_arm64.deb
\
focal
\
tst.tar.gz
\
"deb [trusted=yes] http://ports.ubuntu.com/ubuntu-ports/ focal
main restricted universe multiverse" \
"deb [trusted=yes] http://ports.ubuntu.com/ubuntu-ports/ focal-updates
main restricted universe multiverse" \
"deb [trusted=yes] http://ports.ubuntu.com/ubuntu-ports/ focal-backports
main restricted universe multiverse" \
"deb [trusted=yes] http://ports.ubuntu.com/ubuntu-ports/ focal-security
main restricted universe multiverse" \
"deb [trusted=yes] http://packages.ros.org/ros/ubuntu focal main"
This works great. ros-noetic-cv-bridge is an external-apt-repo package.
It Depends: libopencv-dev. Ubuntu/focal ships 4.2, so the requirement
libopencv-dev (<< 4.5) in the meta-package is satisfied.
OK. But let's say I want to add another, also-heinous external repo into
the mix, and I do this:
mmdebstrap
\
--verbose
\
--architectures=arm64
\
--hook-dir=/usr/share/mmdebstrap/hooks/file-mirror-automount
\
--include ./tst-libopencv_1_arm64.deb
\
focal
\
tst.tar.gz
\
"deb [trusted=yes] http://ports.ubuntu.com/ubuntu-ports/ focal
main restricted universe multiverse" \
"deb [trusted=yes] http://ports.ubuntu.com/ubuntu-ports/ focal-updates
main restricted universe multiverse" \
"deb [trusted=yes] http://ports.ubuntu.com/ubuntu-ports/ focal-backports
main restricted universe multiverse" \
"deb [trusted=yes] http://ports.ubuntu.com/ubuntu-ports/ focal-security
main restricted universe multiverse" \
"deb [trusted=yes] https://repo.download.nvidia.com/jetson/common r35.4
main" \
"deb [trusted=yes] https://repo.download.nvidia.com/jetson/t234 r35.4 main"
\
"deb [trusted=yes] http://packages.ros.org/ros/ubuntu focal main"
This is the same command, but I also make some nvidia packages
available. THAT repo ships its own copy of libopencv-dev: version
4.5.xxxxx. When building the image I explicitly do NOT want it to pick
up that version, but to use the normal Ubuntu/focal ones: that
restriction in the meta-package should do that for me. There's no reason
this shouldn't work, and I can easily create this situation with some
apt commands after I chroot into the image. But mmdebstrap cannot create
this image: the above command fails:
The following packages have unmet dependencies:
tst-libopencv : Depends: libopencv-dev (< 4.5) but 4.5.4-8-g3e4c170df4 is to

Suggestions?
Thanks.
