Not intentional at all... It seems derived from the not existence of that Breaks since Focal and removed when applied the same fix.
Searching where the Breaks was added (as it isn't present in Debian's versions), I found it added due to LP #1740892 for Xenial (2.3.5-3*),Artful and Bionic (same debian version for both, 2.4.2-3*), i.e : corosync (2.4.2-3ubuntu1) bionic; urgency=medium * Properly restart corosync and pacemaker together (LP: #1740892) - d/rules: pass --restart-after-upgrade to dh_installinit - d/control: indicate this version breaks all older pacemaker, to force an upgrade of pacemaker. - d/corosync.postinst: if flagged to do so by pacemaker, start pacemaker on upgrade. + This can be dropped after bionic releases as long as the other changes are maintained. -- Nishanth Aravamudan <nish.aravamu...@canonical.com> Tue, 30 Jan 2018 16:40:31 -0800 Available diffs It seems that the right thing would be to recover the break. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1677684 Title: /usr/bin/corosync-blackbox: 34: /usr/bin/corosync-blackbox: qb- blackbox: not found To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/corosync/+bug/1677684/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
