< Problem: Just as I upgraded my ubuntu 13.10 to 14.04 LTS. I couldn't pass keyring and bash authentication. I can login in recovery mood for both root and my account, but that's not the case in the gnome. Every time I login with sudo, the bash response: "Sorry, try again." If I login in the terminal with su, it says: "Authentication failure" even when I lock the desktop, I can't login in the gnome, while I can do that with ctr+alt+f1 in tty1.
I'm pretty sure from the keys, caps is off, num is on, my account is already added to sudoers file and so on. help me in this, please.
Thanks in advance.
