[SOLVED] quotaon.service failed

After upgrading my system from Wheezy to Jessie the quotaon.service shows as failed. Any clue?

Thanks,
Yves

 

I solved this using
quotaoff /
service quota start

 

My previous fix was wrong...
The problem is a conflict from quotaon.service installed by systemd and the quote.service installed by quota.
I have disabled the quotaon.service by:
cd /etc/systemd/system
ln -s /dev/null quotaon.service
