affects me too after upgrading from Lubuntu 15.04 to 15.10.
Tried to reinstall the package because with "systemd-analyze" I get the answer: "boot not yet finished. Try later".
In fact, the boot finishes after 20 min.
I traced the problem back to mysql.service. Consequently, I tried to re - install mysql-server-5.6.0
