Last Modified: 2013-08-09
I get this when I try to do something as sudo.
sudo: must be setuid root

following some advice I went into recovery mode, and from command line as root
I tried:

chmod 4111 /usr/bin/sudo

and I could not do this, it said its a read only file system.

How can I get sudo back?
