Package: perl-modules-5.22 Version: 5.22.1-2 Severity: serious After the upgrade to perl 5.22, the Module::Build module is no longer present. With perl 5.20, it was present in both perl-modules and libmodule-build-perl. After the upgrade, it is no longer in perl-modules-5.22, and libmodule-build-perl automatically gets removed by aptitude because it is no longer recommended, so that the module is no longer present at all.
Other modules might be affected by the same problem. I could see many packages that were removed, but I don't know which ones were redundant. The upgrade should not remove any module that can still be useful (perhaps unless this is announced in the NEWS.Debian file, so that the user has a chance to reinstall what needs be before he's wondering what's wrong). -- System Information: Debian Release: stretch/sid APT prefers stable-updates APT policy: (500, 'stable-updates'), (500, 'unstable'), (500, 'testing'), (500, 'stable'), (1, 'experimental') Architecture: amd64 (x86_64) Kernel: Linux 4.3.0-1-amd64 (SMP w/8 CPU cores) Locale: LANG=POSIX, LC_CTYPE=en_US.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Init: systemd (via /run/systemd/system) Versions of packages perl-modules-5.22 depends on: ii dpkg 1.18.3 ii perl-base 5.22.1-2 Versions of packages perl-modules-5.22 recommends: ii perl 5.22.1-2 perl-modules-5.22 suggests no packages. -- no debconf information
