Comment 3 for bug 1651883

Thank you for taking the time to report this bug and helping to make Ubuntu better. The relevant dpkg terminal log says:

cp: omitting directory '/etc/udev/rules.d/70-persistent-net.rules'
E: /usr/share/initramfs-tools/hooks/udev failed with return 1.

The udev hook comes from the udev package. So re-assigning to the systemd source package.
