Thanks for the patch. I've applied it to a temporary git branch for now, see below. Since the previous upload (1.0.4-1 in 2023-06) two unrelated bugs have been found and fixed, so it would be good to get these in as well. Do you want me to adjust the debian/changelog to mention these fixes before merging the temporary branch? > If you have any concerns about this patch, please reach out ASAP. No concerns but some questions: * The tfortune package depends on liblopsub and currently has Depends: ${shlibs:Depends}, liblopsub1, ${misc:Depends} in its own debian/control file. When would be the best time to replace liblopsub1 by liblopsub1t64? * Why did you call the new version 1.0.4-1.1? Why not 1.0.5-1 instead? * Do I need to do anything else to get this going besides merging the branch and pushing it to the public repo? Thanks Andre --- commit 806c7a89423cf70c1593325de24be0b160ffde96 Author: Steve Langasek <vor...@debian.org> Date: Thu Feb 1 12:47:49 2024 +0100 64-bit time_t transition. As part of the 64-bit time_t transition required to support 32-bit architectures in 2038 and beyond (https://wiki.debian.org/ReleaseGoals/64bit-time), we have identified liblopsub as a source package shipping runtime libraries whose ABI either is affected by the change in size of time_t, or could not be analyzed via abi-compliance-checker (and therefore to be on the safe side we assume is affected). To ensure that inconsistent combinations of libraries with their reverse-dependencies are never installed together, it is necessary to have a library transition, which is most easily done by renaming the runtime library package. Since turning on 64-bit time_t is being handled centrally through a change to the default dpkg-buildflags (https://bugs.debian.org/1037136), it is important that libraries affected by this ABI change all be uploaded close together in time. Therefore I have prepared a 0-day NMU for liblopsub which will initially be uploaded to experimental if possible, then to unstable after packages have cleared binary NEW.
