Having a closer look, this sounds like a real regression in systemd-udev. Please double-check that "ReceiveChecksumOffload=" (inside a .link) file is working properly with systemd v256
Netplan's tests seem to work otherwise, except when the new systemd is pulled in. It fails for Netplan's sd-networkd & NetworkManager backends, because both make use of systemd-udev .link files. There's no special handling for NetworkManager here. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2066344 Title: netplan.io: autopkgtest fails with systemd 256 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/netplan.io/+bug/2066344/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
