Broken 14.10 -> 15.04 upgrade (systemd problem?)

[edantes2]

I tried to upgrade a 14.10 intallation to 15.04 using the official Ubuntu software update. After reboot, selected default Ubuntu from the grub menu, system boots immediately to "emergency mode". The error message is

[FAILED] Failed to start Load/Save Random Seed
See "systemctl status systemd-random-seed.service" for details

Short of reinstalling 15.04 from scratch, is there an easy fix in the configs?

Merci d'avance!
