# Configurate SSHD to temporarily allow root login with password
sudo nano /etc/ssh/sshd_config
sudo systemctl restart sshd
cp /home/debian/.ssh/authorized_keys /root/.ssh/authorized_keys
# 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]
cp /root/.ssh/authorized_keys /home/[user]/.ssh/authorized_keys
# SSH to [user]
sudo rm /root/.ssh/authorized_keys
sudo passwd -dl root
# Disable root in SSHD
sudo nano /etc/ssh/sshd_config
