Hi, during a test with piuparts I noticed your package fails to upgrade from 'stable'. It installed fine in 'stable', then the upgrade to 'sid' fails because it tries to overwrite other packages files without declaring a Breaks+Replaces relation. See policy 7.6 at https://www.debian.org/doc/debian-policy/ch-relationships.html#overwriting-files-and-replacing-packages-replaces This test intentionally skipped 'testing' to find file overwrite problems before packages migrate from 'unstable' to 'testing'. >From the attached log (scroll to the bottom...): Preparing to unpack .../0-libocct-foundation-7.5_7.5.0+dfsg1-1_amd64.deb ...

So why is the package naming following MAJOR.MINOR instead of SOVERSION? The latter would ease maintenance by avoiding lots of Breaks+Replaces in the future. This is probably the same for all the packages shipping opencascade shared libraries. cheers, Andreas PS: If the libraries from 7.3 and 7.5 are not exchangeable (i.e. not API and ABI compatible), they should not have the same SOVERSION.
