The Debian bug is marked as fixed, however unfortunately it seems to have 'fixed' the problem simply by adding Recommends: nscd to the ypbind-mt package, which only actually fixes things if the systemd admin does install/use nscd. If the admin chooses not to use nscd, this bug still exists.

However, Debian and Ubuntu don't enable/provide systemd-userdb, so that design does not work for Debian/Ubuntu. this also can cause systemd-udevd failures in some cases as well, apparently (based on upstream and debian discussion comments) For reference, upstream discussion around the systemd-logind sandboxing specifically: https://github.com/systemd/systemd/issues/7074 upstream updated doc PR explaining the upstream position: https://github.com/systemd/systemd/pull/7343 Debian bug report: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=878625 To manage notifications about this bug go to: https://bugs.launchpad.net/systemd/+bug/1934393/+subscriptions -- Mailing list: https://launchpad.net/~touch-packages Post to : touch-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~touch-packages More help : https://help.launchpad.net/ListHelp
