nextcloud systemd-udevd[9034]: Could not generate persistent MAC address for veth4c59f06: No such file or directory.
Environment (optional)
UCS: 4.4-8 errata1166

Solution
Please compare the Linux Kernel Version of the previous host system and adjust it accordingly if necessary, before you proceed with any further investigation.
