A problem has been identified with ubuntu25 with users using the OBS binary sources.
Install package home:gambas:master / gambas3
Install package home:gambas:stable / gambas3

after running the command
sudo apt modernize-sources

The problem was the gpg signature for the repository was not added to the now used .sources file.

So it looked like this..  (master version)

cat /etc/apt/sources.list.d/home:gambas:master.sources

The issue is the Signed-By: field is blank and needs to point to the gpg signature file.

If you followed the instructions on the OBS site then the signature file will be in /etc/apt/trusted.gpg.d/

so your file should be more like this.. (replace the words master for stable if you install the stable version)

With the Signed-By field pointing to the correct file "apt update" and "apt install gambas3" will then work correctly.

That is because OSB uses this weird syntax that is not according to Debian standards, and thus the modernize-sources partly fails.
OSB is weird when it comes to their implementation of debian repositories. I think their mindset and approach is based on openSuSe repository logic, not Debian repository logic.

And it should actually look like this IMHO and understanding of the matter:

Code

Types: deb
URIs: http://download.opensuse.org/repositories/home:/gambas:/master/xUbuntu_25.04/
Suites: plucky
Components: main
Signed-By: /etc/apt/trusted.gpg.d/home_gambas_master.gpg


But that fails so don't do that…

I wrote should and that OSB is a weird implementation using / for suites and leaving components empty. But that's the way and the info they provide for modernizing, no wonder it fails. So, not providing a different solution, just pointing out weirdness from a debian perspective and the possible reason why modernize fails.

It's a very unique approach. If you look at old ubuntu ppa and their sources files, they did it as it should be and they would probably modernize without any issues

hehe, yeah it's cool m8, i just thought i better add that so nobody tried it

I guess there's bound to be some translation differences with how OpenSuse packaging system works and other systems do it.

Thank heavens there's experts like us on the case eh
