Bug#739663: libboinc7: fails to upgrade from 'wheezy' - trying to overwrite /usr/lib/libboinc_zip.so.7

[Andreas Beckmann]

Package: libboinc7
Version: 7.2.39+dfsg-1
Severity: serious
User: debian-qa at lists.debian.org
Usertags: piuparts
Control: affects -1 + boinc-dev

Hi,

during a test with piuparts I noticed your package fails to upgrade from
'wheezy'.
It installed fine in 'wheezy', then the upgrade to 'jessie' fails
because it tries to overwrite other packages files without declaring a
Breaks+Replaces relation.

See policy 7.6 at
http://www.debian.org/doc/debian-policy/ch-relationships.html#s-replaces
