Can't Sudo or get to root

[Mike_Hughes]

When I try to go to sudo su I get the following error - sudo: /usr/bin/sudo must be owned by uid 0 and have the setuid bit set
macmike@ubuntuServer:/usr$. Was working just start this error. What do I do to fix this one. I can't start the server and log in as root either. I can't ssh in as root either. Gives me permission denied. I tried resetting root password and it will not let me. My mysql server will not start either.

I try to do anything with sudo I get - sudo: /usr/bin/sudo must be owned by uid 0 and have the setuid bit set
I tried to chown and says not permitted.

Run in terminal

ls -l /usr/bin/sudo
And paste back the return here.

'sudo' is only used to grant root privileges, and must be followed by a command
