"su" Command Not Working

[memaster3]

Here is what happens.

I type in "su", without the quotes, to switch to root. I enter my password.

jon-Tuxbox:~$ su
Password: 
su: Authentication failure
jon-Tuxbox:~$

It fails, and I get kicked back to the command line. I recently fixed the permissions on the shadows file and the su file in the bin directory, and that is what caused this. Before it would give another error. I tried resetting the password for root, but it didn't fix it. Any help would be appreciated.

In ubuntu you use sudo unless you've actually enabled su.

Your password will work with sudo.

I'm not stupid. I enabled su with sudo passwd. I recently had some problems with both sudo and su, and when I fixed them, this happened. I tried sudo passwd again, and it didn't fix it.

Shame you couldn't be bothered to say what you'd done in the first place in order to help people help you.

You might not be stupid but you are rude - good luck.
