Public bug reported: Info: Ubuntu Server 18.04 LTS, 4.15.0-43-generic, fresh installation (December, 2018). HP DL380 server
I had this issue already twice in the past couple of months. After unattended upgrade of systemd my server's public IP address is removed from the interface. I statically configure the IP address using the interfaces file. I have opted out of the YML based network configuration. This is my apt history log: Start-Date: 2019-04-09 06:15:01 Commandline: /usr/bin/unattended-upgrade Upgrade: systemd-sysv:amd64 (237-3ubuntu10.13, 237-3ubuntu10.19) End-Date: 2019-04-09 06:15:07 Start-Date: 2019-04-09 06:15:12 Commandline: /usr/bin/unattended-upgrade Upgrade: udev:amd64 (237-3ubuntu10.13, 237-3ubuntu10.19), libudev1:amd64 (237-3ubuntu10.13, 237-3ubuntu10.19) End-Date: 2019-04-09 06:15:56 Start-Date: 2019-04-09 06:15:59 Commandline: /usr/bin/unattended-upgrade Upgrade: libsystemd0:amd64 (237-3ubuntu10.13, 237-3ubuntu10.19), libpam-systemd:amd64 (237-3ubuntu10.13, 237-3ubuntu10.19), systemd:amd64 (237-3ubuntu10.13, 237-3ubuntu10.19), libnss-systemd:amd64 (237-3ubuntu10.13, 237-3ubuntu10.19) End-Date: 2019-04-09 06:16:15 After that my server was unavailable from the Internet. When I logged in via out of band management and simply brought down and up the interface everything went back to normal. As said above this is the second time I had this issue. Last time it was unattended upgrades and it was systemd again. ** Affects: systemd (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1823871 Title: After unattended-upgrade of systemd IP configuration removed from interfaces To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/systemd/+bug/1823871/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
