Bom dia, estou com um problema estranho.
Usava até ontem o Debian 9 para acessar os roteadores do meu serviço por SSH.
Aí resolvi trocar para o Ubuntu 18 e não consigo acesso aos roteadores por causa da versão do Openssh.
Quando tento acesso, recebo a mensagem: ssh_dispatch_run_fatal: Connection to <IP> port 22: Invalid key length.
Alguem ja teve esse problema?
