I have one user account on my laptop, and it has the same password as the su password. I changed the user account to an auto login account, and now the user password is not accepted (i.e. authentication error) for installations, updates... anything. I'm sure I haven't forgotten the password, and pretty sure I haven't dorked up some setting by logging in as root since I normally have to enter the su password to install updates. When I login and am prompted to enter my password to unlock the user keyring, the password works.
I fear that all efforts will be hampered because I can't get to the su level of control. Help?
Attempts thus far:
Tried this fix, which sounds very simliar - don't have 'clown' command available: Setup auto login and now I do not have root authorization for anything
Tried the simple 'passwd username' without luck – 'Authentication token manipulation error'
