Em um novo Ubuntu 16.04 LTS instalar depois de instalar o nginx, php, mysql Eu estava tentando instalar o ufw.
Primeiro, quando tentei permitir a Port 22 / OpenSSH, me deparei com um erro do iptables.
ERROR: initcaps
[Errno 2] iptables: Memory allocation problem.
Após algumas pesquisas, experimentei os comandos
iptables -F
iptables -X
e executou o comando novamente. Agora parecia funcionar.
Então eu tentei executar o sudo nfw enable e continuo recebendo esta mensagem de erro infelizmente:
sudo ufw enable
Command may disrupt existing ssh connections. Proceed with operation (y|n)? y
ERROR: problem running ufw-init

Sou relativamente novo nisso, então não consigo descobrir quais são os problemas aqui.
Obrigado!
