Hello everybody! Every now and then we have the problem that packages that we are building in our Science:EtherLab repository [1] are built against newer libraries, that are not available on a live system (or in the current Docker image) and the packages are not installable. This problem recently appeared again (see two examples below). That leads us to the general question: Which paths must be configured for the repositories in OBS so that the same packages are available that are also available in a live installation or in a current Docker image? We keep stumbling across the fact that our packages built in the Science:EtherLab project cannot be installed because dependencies cannot be fulfilled. [1] https://build.opensuse.org/repositories/science:EtherLab # Example 1 (Container) Repository: Leap 15.4 (x86_64) Repository paths: - openSUSE:Leap:15.4:Update/standard Package: Data Logging Service (DLS) https://build.opensuse.org/package/show/science:EtherLab/DLS During the build process the build system pulls the library libprotobuf25 and creates a dependency to libprotobuf.so.25.1.0()(64bit) later on: [ 9s] [213/389] cumulate libprotobuf25_1_0-25.1-150400.9.3.1 https://build.opensuse.org/projects/science:EtherLab/packages/DLS/repositori... However, only the libprotobuf20 version is offered in the current container image, so the DLS package cannot be installed. $ docker pull opensuse/leap:15.4 $ docker run --rm -it opensuse/leap:15.4 e5757d974480:/ # zypper sh zypper> se -s protobuf2 ...

But we don't get, where the build containers pull the different kernel versions / library versions from. Can anyone help? Thanks a lot, Florian
