was playing around with "User accounts" and I made same mistake, I got in same hole.
You just set your system to no-password when "playing around".
That's why your system log in (auto or not) without asking for password, and this is the same reason keyring system asks for it (cause doesn't received from the system).
So, action jackson:
- Check what I am talking about. Go to Menu in Top Bar and choose 1st item (Switch User Account...) and see Login button (what mean you already logged and no user to choose, u can just login, u have no pass (OH!)
- After clicking Login, and back to desktop, Choose again in top menu bar the logout command, and logout. You gonna see a button with your username, no "login" button.
- Correcting things: Setting a new password. Set the same old one, to keyring dont get confused again, or it will ask you for the password again, after login with password provided. Go to same menu of item 1 and choose last item now (User Accounts...) and on this Gui interface , unlock on the respective button probably providing no password at all (just Enter, if this not works try with old pass..), and then THE GREAT MAGIC TRICK
CLICK THE PASSWORD BOX (its a hidden button, oh devil UI)
this open a dialog box (!) where u probably hit the "login without password" option AND with automatic login option ON too (outside this dialog, on User Accounts screen). SO:...
When you tell the computer to log in without a password (ITS NOT the same as Automatic Login) he does exactly this , log in, without password. So password = nothing. Then keyring goes crazy. (aha!) So, choose the right option now:
Set a password now
and after doing all the entry password stuff, simple hit enter, set automatic login off, to feel again the pleasure of having a password, and if you want it on again, ok, turn it on, but dont log in without a password again. =D
I hope this helps you to solve your problem. Was a good lesson to me. Bad UI to Ubuntu -1 on this case.
