Update 1.5.8 to 1.5.9 on Ubuntu 14.04

[Lenain]

Hello,
I have a error while updating fog from 1.5.8 to 1.5.9 on Ubuntu 14.04 LTS:

Setting up and starting MySQL......................
/lib/common/functions.sh line 1095: systemctl command not found
/lib/common/functions.sh line 1096: systemctl command not found

I have opened the script and lines 1095 and 1096 are:

dbservice=$(systemctl list-units | grep -o -e "mariadb\.service" -e "mysqld\.service" -e "mysql\.service" | tr -d '@')
[[ -z $dbservice ]] && dbservice=$(systemctl list-unit-files | grep -v bad | grep -o -e "mariadb\.service" -e "mysqld\.service" -e "mysql\.service" | tr -d '@')

I have roleback to a snapshot in case, is it a serious bug or just a warning?
Thank you
