It's the first time this happened. On regular terminal my login works great, even as root. My user name is always the same (Júnior) and login in never was a problem. I even tried setting the root passwd but nothing helps.
I cant login normally in the Terminal in both my username and as root.
BTW this happended after I started to install the system with a 21 characters password with numbers (upper and lower case) and symbols = (example) - fR81@@#$Jjase(*81$4
