Package: libclamav11 Version: 1.0.0+dfsg-1 Severity: serious User: debian...@lists.debian.org Usertags: piuparts
Hi, during a test with piuparts I noticed your package fails to upgrade from 'sid' to 'experimental'. It installed fine in 'sid', then the upgrade to 'experimental' fails because it tries to overwrite other packages files without declaring a Breaks+Replaces relation. This error may also be triggered by having a predecessor package from 'sid' installed while installing the package from 'experimental'. See policy 7.6 at https://www.debian.org/doc/debian-policy/ch-relationships.html#overwriting-files-and-replacing-packages-replaces >From the attached log (scroll to the bottom...): Preparing to unpack .../libclamav11_1.0.0+dfsg-1_amd64.deb ... Unpacking libclamav11:amd64 (1.0.0+dfsg-1) ... dpkg: error processing archive /var/cache/apt/archives/libclamav11_1.0.0+dfsg-1_amd64.deb (--unpack): trying to overwrite '/usr/lib/x86_64-linux-gnu/libfreshclam.so.2', which is also in package libclamav9:amd64 0.103.7+dfsg-1+b2 Errors were encountered while processing: /var/cache/apt/archives/libclamav11_1.0.0+dfsg-1_amd64.deb Mixing libraries with different soversions in a single package is not a good idea as can be seen here. Having to add Breaks+Replaces between shared library packages also makes (future) transitions more difficult. Please move libfreshclam.so.2 to a new libfreshclam2 package and add Breaks+Replaces: libclamav9 (<< 1), libclamav11 (<< 1.0.0+dfsg-2) there. (The transition to libclamav11 will be not smooth, but future transitions will be.) cheers, Andreas
