Comment 31 for bug 1579580

You can rid of it by:

systemctl stop ureadahead.service
systemctl disable ureadahead.service
apt-get purge ureadahead.service
Reboot

Check to see if it is running
systemctl status ureadhead.service
ps aux | grep ureadahead

It should be gone.

18.10 is coming out in a few weeks. You can scrub your system and start anew. Download a 18.10 beta daily build and try it, or wait until release.
