Public bug reported: [Impact] The IPv6 configuration is being cleared even though `KeepConfiguration` is set to `yes`, causing the iSCSI backend system to hang during shutdown.
[Fix] Systemd upstream has addressed this issue. https://github.com/systemd/systemd/pull/34989 [Test Plan] 1. Set up a machine with an iSCSI backend in an IPv6-only environment. 2. Configure the `KeepConfiguration` option for each network device individually using drop-in configuration files (e.g., `/etc/systemd/network/*.network.d/*.conf`) or set the `"critical"` option to `true` in the Netplan configuration. 3. Power off the machine and verify that the system does not hang. [Where problems could occur] The patches ensure that DHCPv6 addresses are preserved when `KeepConfiguration=yes` is set. However, if any regressions occur, the IPv6 connection may be impacted. ** Affects: systemd (Ubuntu) Importance: Undecided Status: New -- 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/2098183 Title: Preserve IPv6 configurations when `KeepConfiguration=dhcp-on-stop` is set Status in systemd package in Ubuntu: New Bug description: [Impact] The IPv6 configuration is being cleared even though `KeepConfiguration` is set to `yes`, causing the iSCSI backend system to hang during shutdown.
