Olá pra tod em s,

Por intermédio do Thiago consegui resolver o problema da conexão. ele teve
um problema]
similar e a solução estava na senha, pois pensei que puesse usaar qualquer
tipo de caracter,
mas acabei de aprender que não. Ao trocar a  senha usando usando caracteres
normais a
conexão foi feita.
Naveguei um pouco e para confirmar, reiniciei o laptop e voilá, tudo ok!!

É por essa e outras que minha decisão e trocar de SO foi acertada!!

Valeu Ubunteiros!!!!

Obrigado a todos pela ajuda e um abraço ao Thiago!!
