Package: release.debian.org Severity: normal User: release.debian....@packages.debian.org Usertags: transition
I would like to start a transition for ncurses, changing the soname of the libraries from 5 to 6. This affects a large number of packages (about 600 of them), but should be doable almost exclusively via binNMUs, with two exceptions: - libcdk5 needs a sourceful upload and a rename of the library package, neither this package nor its three reverse dependencies should be rebuilt before that. Please see https://bugs.debian.org/892280 and https://release.debian.org/transitions/html/auto-libcdk5.html. - cwidget also needs a sourceful upload and either a package rename or a shlibs bump + versioned Breaks against aptitude, please see https://bugs.debian.org/891161 for details. Fortunately both cwidget and aptitude currently FTBFS with libncursesw6, so there is no danger of incompatible combinations after binNMUs. The packages libtinfo5, libncurses5 and libncursesw5 are still built, so only packages depending on the multilib packages and the udeb become uninstallable and need to be rebuilt right away: grub, readline and screen. Apart from cwidget/aptitude, I have not noticed any ncurses related FTBFS bugs, and the API is unchanged. However, there will certainly be quite a few unrelated FTBFS problems, such as the recent switch to openjdk-9 and the python3.6/python3-distutils breakage.
