[Touch-packages] [Bug 2011458] Autopkgtest regression report (openssh/1:9.0p1-1ubuntu7.2)
All autopkgtests for the newly accepted openssh (1:9.0p1-1ubuntu7.2) for kinetic have finished running. The following regressions have been reported in tests triggered by the package: hg-git/0.10.4-3 (amd64, arm64, armhf, ppc64el, s390x) piuparts/1.1.5 (amd64, arm64, ppc64el, s390x) sbuild/0.83.1ubuntu1 (arm64, ppc64el, s390x) Please visit the excuses page listed below and investigate the failures, proceeding afterwards as per the StableReleaseUpdates policy regarding autopkgtest regressions [1]. https://people.canonical.com/~ubuntu-archive/proposed- migration/kinetic/update_excuses.html#openssh [1] https://wiki.ubuntu.com/StableReleaseUpdates#Autopkgtest_Regressions Thank you! -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to openssh in Ubuntu. https://bugs.launchpad.net/bugs/2011458 Title: ssh fails to rebind when it is killed with -HUP Status in openssh package in Ubuntu: Fix Released Status in openssh source package in Kinetic: Fix Committed Status in openssh source package in Lunar: Fix Committed Bug description: [Impact] The sshd re-execution logic is generally broken with systemd socket activation, which means that (1) sshd fails when it is told to re-exec via SIGHUP (e.g. systemctl reload ssh), and (2) sshd fails when started in debug mode.
