[Touch-packages] [Bug 1824806] Re: Network stops working after systemd update
So I tested... $ sudo systemctl restart systemd-networkd ... and got the same results - the "speed changed to 0 for port" messages and loss of connectivity requiring a reboot. Afterwards, however, I noticed that I was not completely up to date so I ran an `apt full-upgrade` which brought in the latest systemd packages (237-3ubuntu10.20). During the upgrade I again saw the "speed changed to 0 for port" message and I had to reboot in order to restore connectivity. Now when I run either test (`systemctl restart systemd-networkd` or `systemctl stop systemd-networkd`), the message does not appear and I do not lose connectivity. To rule out that it only appears to occur during an upgrade, I noticed that systemd has an update in proposed (237-3ubuntu10.21), so I enabled that repository, did an `apt update` followed by an `apt full-upgrade` and the install went perfectly. So this may very well have been fixed by 237-3ubuntu10.20, but I don't want to speak for the original reporter. Side note: after running `systemctl stop systemd-networkd` the systemd- networkd process disappears from my process list, but the network does not get brought down. I don't know if that is intended behavior, but in either case it is not directly related to this report. -- 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/1824806 Title: Network stops working after systemd update Status in systemd package in Ubuntu: Confirmed Bug description: I have four 18.04 servers that are regularly updated and have a bond/bridge configured via netplan.

Not the reporter but having a similar issue. When the systemd package is updated my bond dies (with the "speed changed to 0 for port" message). Nothing that I have tried to restore the network connection worked short of a full reboot. I have attached my syslog showing what occurs during the upgrade. I also see the following during this time: bond1: Warning: No 802.3ad response from the link partner for any adapters in the bond The LACP configuration on the switch is identical for all servers with bonds, but the only ones having this problem are the ones running bionic (trusty & xenial are unaffected). I will try to find some time to see if I can reproduce with a simple 'systemctl restart systemd-networkd' -- 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/1824806 Title: Network stops working after systemd update Status in systemd package in Ubuntu: Confirmed Bug description: I have four 18.04 servers that are regularly updated and have a bond/bridge configured via netplan.

do you notice similar (problematic) behavior when just restarting networkd, e.g.: $ sudo systemctl restart systemd-networkd or, stopping systemd-networkd, e.g.: $ sudo systemctl stop systemd-networkd -- 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/1824806 Title: Network stops working after systemd update Status in systemd package in Ubuntu: New Bug description: I have four 18.04 servers that are regularly updated and have a bond/bridge configured via netplan.
