All autopkgtests for the newly accepted systemd (240-6ubuntu5.8) for disco have finished running. The following regressions have been reported in tests triggered by the package:
prometheus-bind-exporter/unknown (armhf) php7.2/7.2.24-0ubuntu0.19.04.1 (armhf) gvfs/1.40.1-1ubuntu0.1 (ppc64el) pdns-recursor/unknown (armhf) webhook/unknown (armhf) munin/2.0.47-1ubuntu3 (armhf, arm64) systemd/240-6ubuntu5.8 (ppc64el) 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/disco/update_excuses.html#systemd [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 systemd in Ubuntu. https://bugs.launchpad.net/bugs/1849658 Title: resolved fallback to TCP fails for truncated UDP replies Status in systemd package in Ubuntu: Fix Released Status in systemd source package in Disco: Fix Committed Status in systemd source package in Eoan: Fix Committed Status in systemd source package in Focal: Fix Released Bug description: [impact] for DNS UDP replies larger than 512 bytes, fallback to TCP is used. For example 'host toomany.ddstreet.org'. Due to a bug in resolved in refcounting DNS stream types, the refcount underflows for type 0 streams (which resolved uses to talk to upstream nameservers), resulting in resolved being unable to fallback to TCP to handle truncated UDP replies.

[other info] https://github.com/systemd/systemd/pull/13838 The commit adding stream types is not present in x/b, so this is needed only for disco and later.
