Before running

To install Debian on Oracle Cloud, refer to this documentation.

On a fresh Debian system, replace the default debian user:

# Give root account a password
sudo passwd root

# Configurate SSHD to temporarily allow root login with password
sudo nano /etc/ssh/sshd_config.d/sshd.conf

# Login as root, add new user and delete debian user
su root
sudo groupmod -n [user] debian
sudo usermod -l [user] debian
sudo usermod -d /home/[user] -m [user]
sudo passwd [user]
sudo userdel debian
sudo rm -r /home/debian

# Switched [user] 
su [user]
sudo passwd -dl root

# Configurate SSHD again to allow [user] login and to set a custom port
sudo nano /etc/ssh/sshd_config.d/sshd.conf
