Could you please share the output of followings:
hostname -f && hostname -i && getent hosts $(hostname -f) && cat /etc/hosts

127.0.0.1 localhost

There are some issues in your hostname and /etc/hosts configuration. Try followings:
- Always use FQDN format when setting hostname; for example- mail.exmaple.com
- Configure /etc/hosts as instructed in the official documentation. Link
So in short:
hostnamectl set-hostname mail.example.com # Remove unnecessary things from /etc/hosts > /etc/hosts # Add recommended entries to /etc/hosts cat <<EOF>> /etc/hosts 127.0.0.1 localhost 192.168.0.51 mail.example.com mail EOF # Check /etc/hosts after configuration cat/ etc/hosts
- Do not leave any ipv6 references in /etc/hosts
Now what causes the issue you encountered, to begin with:
among few things, one of them is when you execute the service-discover setup-wizard it tries to connect to your ldap via resolving your hostname and IP address. And when /etc/hosts are not properly configured, then it fails to resolve.
Hope it helps.
