Foreman » Packaging

Hello,

when I try to install the foreman with the katello scenario by this command

foreman-installer --scenario katello \
--foreman-initial-organization "Capensis" \
--foreman-initial-location "Lille" \
--foreman-proxy-content-puppet=false \
--puppet-agent=false \
--no-enable-puppet \
--puppet-server=false \
--puppet-server-ca=false \
--foreman-proxy-puppet=false \
--foreman-proxy-puppetca=false \
--foreman-proxy-manage-puppet-group=false \
--foreman-proxy-dhcp=false \
--foreman-proxy-dns=false \
--foreman-proxy-tftp=false \
--foreman-puppetrun=false

I get an error telling the candlepin server can't start because : Unsupported major.minor version 52.0

For the installation to succeed, I have to do this.

yum install java-1.8.0-openjdk -y

Technical environment :

Centos 7.5.1804
Foreman 1.19.0-1
Katello 3.8.0-5

Thanks in advance.
Rgs,
