It throw error

root@box:/opt/mailcow-dockerized# sudo install fail2ban -->> sudo apt-get install fail2ban
sudo install ufw -->> sudo apt-get install ufw
sudu ufw default deny incomoing -->> sudu ufw default deny incoming
sudo ufw default allow outgoins -->> sudo ufw default allow outgoing
install: target 'fail2ban' is not a directory
install: target 'ufw' is not a directory
Command 'sudu' not found, did you mean:
  command 'tudu' from deb tudu (0.10.4-1)
  command 'sudo' from deb sudo (1.9.9-1ubuntu2.4)
  command 'sudo' from deb sudo-ldap (1.9.9-1ubuntu2.4)
Try: apt install <deb name>
ERROR: Invalid syntax

I think you need
sudo apt-get install fail2ban
sudo apt-get install ufw
sudo ufw default deny incoming
sudo ufw default allow outgoing

Also somebody know how to fix this error?
