Re: APT Pinning Broken?

[Andreas Heinlein <aheinlein@gmx.com>]

Hello,

it does make sense in the way that manually installing e.g. libavcodec61 with "apt-get install libavcodec61" and automatically installing it as a dependency produces the same results.

What was apt expected to do if something else already had pulled in libavcodec61 from bookworm? Upgrade it, potentially breaking the other package? Leave it alone? You need to tell it somehow.

I know this is sometimes tricky. I ended up multiple times downloading the source package from sid and rebuilding it for the current stable just to solve these dependency problems.

Hello Andreas, thanks for the reply!

The problem with adding mpv's dependencies to list.pref.chroot​ is that the same error will occur again for the dependencies of those dependencies.

 libasound2t64 : Depends: libasound2-data (>= 1.2.12-1) but 1.2.8-1 is to be installed

 libavcodec61 : Depends: libcodec2-1.2 (>= 1.2.0) but it is not installable

                Depends: libdav1d7 (>= 1.1.0) but it is not installable

                Depends: libglib2.0-0t64 (>= 2.12.0) but it is not installable

                Depends: libjxl0.9 (>= 0.8.0) but it is not installable

                Depends: librav1e0.7 (>= 0.5.1) but it is not installable

                Depends: libsnappy1v5 (>= 1.2.1) but 1.1.9-3 is to be installed

                Depends: libsvtav1enc2 (>= 2.1.0+dfsg) but it is not installable

                Depends: libvpl2 (>= 2023.3.0) but 2023.1.1-1 is to be installed

                Depends: libvpx9 (>= 1.12.0) but it is not installable

                Depends: libwebp7 (>= 1.4.0) but 1.2.4-0.2+deb12u1 is to be installed

                Depends: libwebpmux3 (>= 1.4.0) but 1.2.4-0.2+deb12u1 is to be installed

                Depends: libx264-164 (>= 2:0.164.3108+git31e19f9)

                ............

I tracked down every single dependency (and their dependencies) with this:

apt-cache depends --recurse --no-recommends --no-suggests --no-conflicts --no-breaks --no-replaces --no-enhances mpv | grep "^\w" | sort -u​

Then I added them to list.pref.chroot but the error always comes back for something else.


Package: mpv libasound2t64 libavcodec61 libavdevice61 libavfilter10 libavformat61 .......​

I found a dirty fix with a live.chroot.hook​ that installs mpv from unstable and includes the correct dependencies from unstable too:

apt-get install -y mpv/unstable

But that's not a solution. I would really like to understand why APT Pinning does not or cannot include the dependencies of a package from the release it is pinned to. Doesn't even make any sense tbh.

Hello,

you will have to manually pin the dependencies as well. So it should read:

Package: mpv libasound2t64 libavcodec61 libavdevice61 libavfilter10 libavformat61
Pin: release n=sid
Pin-Priority: 600

That should do the trick.

Hello, I would like to build with bookworm as the distribution while installing the package mpv and ffmpeg from sid (unstable).

According to the Debian Live Manual this should do the trick:

config/archives/live.list.chroot​

deb http://deb.debian.org/debian sid main

config/archives/live.pref.chroot​

Package: mpv

Pin: release n=sid

Pin-Priority: 600

Package: *

Pin: release n=sid

Pin-Priority: 1

This gives a low version error because live-build tries to install mpv's dependencies from bookworm release, which has default Priority 500, while sid now only has Priority 1 for anything but mpv.

The following packages have unmet dependencies:

 mpv : Depends: libarchive13t64 (>= 3.4.0) but it is not going to be installed

       Depends: libasound2t64 (>= 1.0.27)

       Depends: libavcodec61 (>= 7:7.0)

       Depends: libavdevice61 (>= 7:7.0) but it is not going to be installed

       Depends: libavfilter10 (>= 7:7.0)

       Depends: libavformat61 (>= 7:7.0)

.......

If I set the sid Priority higher or equal to bookworm's, all packages are installed from sid because of higher version numbers.

Is there a way to only install mpv including its dependencies from sid, while all other packages are still installed from bookworm release?

Thank you so much and have a nice day!
