Solved Unable to find a source package for freeorion

[CaffeineAddict]

I'm trying to build a package from unstable branch called freeorion.
The instructions which I'm following are here: https://wiki.debian.org/SimpleBackportCreation

rmadison freeorion --architecture amd64
freeorion  | 0.4.8-1+deb10u1      | oldoldstable | amd64
freeorion  | 0.4.10.1-1+b2        | oldstable    | amd64
freeorion  | 0.4.10.2-1+b7        | stable       | amd64
freeorion  | 0.5+git20230820-4+b3 | testing      | amd64
freeorion  | 0.5+git20230820-4+b3 | unstable     | amd64

My sources.list have these entries:

# Debian testing package sources
deb-src http://deb.debian.org/debian/ testing main

# Debian unstable package sources
deb-src http://deb.debian.org/debian/ unstable main

Then I do:

sudo apt update
apt source freeorion/testing

And get this error:

Reading package lists... Done
E: Can not find version '0.4.10.2-1' of package 'freeorion'
E: Unable to find a source package for freeorion

Taking a look online the package is there:

Debian -- Details of package freeorion in trixie

I also tried pulling the sources from unstable with:

apt source freeorion/unstable

And get the same error.

Any suggestions on how to get around this?
And why can't I download sources if they are reported to be there?

Is this the Game?? if so have you tried the snaps version

Install freeorion on Debian using the Snap Store | Snapcraft

Get the latest version of freeorion for on Debian - turn-based space empire and galactic conquest (4X) computer game

Thank you but I prefer to build it the Debian way because I'm not fan of snaps or flatpaks.

Btw. in the mean time I figured out how to get around this problem, on the link here https://packages.debian.org/trixie/freeorion
on the right side there are 3 archives which can be downloaded from browser.

I downloaded these, extracted them and moved contents from freeorion_0.5+git20230820-4.debian.tar.xz into freeorion_0.5+git20230820.orig.tar.xz then the procedure from SimpleBackportCreation worked just fine.

@osprey
Thanks, I have looked at repository here: https://salsa.debian.org/games-team/freeorion/-/tree/debian/0.5+git20230820-4/debian?ref_type=tags
However directory structure is not the same as in those downloaded archives, so I'm not sure if the source tree would let me create a backport package, it would probably be normal way of compiling it. (not sure)
But your command is useful, didn't know it.

Thank you both for help!
