Package: libant1.5-java Version: 1.5.4-1 Severity: important Hi, you must add Replaces: ant (<< 1.5.4-2) in libant1.5-java declaration to ensure that ant is removed before libant1.5-java is installed. This is explained in policy section 7.3. Currently the upgrade process aborts if ant is upgraded before libant1.5-java. Denis
