logrotate error: stat of /var/log/xferlog failed

In Arch Linux the logrotate service was failing:

user@host# systemctl start logrotate.service 
Job for logrotate.service failed. See "systemctl status logrotate.service" and "journalctl -xe" for details.

So I ran it by hand to debug:

user@host# logrotate /etc/logrotate.conf

And the following error appeared:

logrotate error: stat of /var/log/xferlog failed

I fired up a grep for xferlog in the /etc directory:

user@host:/etc# grep -r xferlog *
logrotate.d/proftpd:/var/log/xferlog

Solution was commenting the xferlog rule in logrotate.d/proftpd. I don’t need the transfer log.
