[Bug 194496] Re: [users-admin] Unlock -> "Could not authenticate. An unexpected error has occurred."

[nidal22]

Hello,
I tried to add Synpatic Package Manager from the Main menu after it disapeared from ( system-> Adminstration), but when I check Synpatic Package Manager, it uncheck by itself, same for other item in (Main Menu->Administration)

My computer crashed yesterday after using hardware test, after booting I
had a problem with $HOME/.dmrc and fixed it. This morring, neither sudo
or gksu are working any more.

I ckecked sudoers file, I get this error

nidal at dell-640m:~$ cat /etc/sudoers
cat: /etc/sudoers: Permission denied

I used revovery mode ( visudo) to check it, I did not find my user name
in the list, I added myself and I checked the file permission: 440, but
still sudo is not working.

Thanks, Nidal
