Error on running foreman-installer -i

Forward DNS points to 127.0.1.1 which is not configured on this server
your system does not meet the configuration criteria

cat /etc/hosts

127.0.0.1 localhost
127.0.1.1 servervm-virtualbox.xxxxx.xxx.com servervm-virtulabox

cat /etc/hostname

servervm-virtualbox

could anyone please help

Try swapping the order of records so localhost is not first. If that doesn’t help, ensure hostname -f returns the FQDN

Hope that helps.
