Package: sgml-base Version: 1.26+nmu2 Severity: serious Justification: breaks reverse dependencies like openjade Owner: helm...@debian.org User: helm...@debian.org Usertags: rebootstrap
In dpkg 1.17.0, trigger processing was changed. Starting with that version, dpkg no longer activates triggers for conffiles on package removal (because conffiles are only removed during purge). Since that version the following sequence in a pristine sid chroot leaves a broken super catalog: apt-get install docutils-common apt-get remove docutils-common The latter invocation does not trigger sgml-base. Thus docutils-common remains in the super catalog and e.g. openjade fails. After discussion this with Guillem Jover, we concluded that this particular use of sgml-base was not intentional, so dpkg will not revert to the 1.16.10 behaviour. Guillem Jover suggested that sgml-base should provide a conffile-independent trigger (e.g. "update-catalog") and that packages providing catalogs should invoke it explicitly. Implementing this implies changing sgml-base, debhelper and reuploading 24 source packages shipping catalogs. A simpler approach is to trigger on the referenced files. For all relevant cases, they reside in /usr/share/sgml or /usr/share/xml. Declaring interest on both locations means triggering on 70 binary packages (i.e. 46 excess). This approach practically fixes the bug with one upload. I intend to pursue a combination of the above: Fix the immediate bug with the second method and update dh_installcatalogs to issue the trigger but skip updating those 24 source packages. I intend to upload the attached patch after gaining more confidence in not causing more breakage. Feedback welcome. Helmut
