[Bug 947738] Re: precise failed to install: unable to initialize policy plugin

Permission denied

That's a very strange error.  sudo should be an suid-root executable,
which means it should have no problem opening /etc/sudoers.

Is this happening when installing from a live CD or from a USB stick?
What's the output of the command 'ls -l /usr/bin/sudo' on this system?
(Have you already rebooted since hitting this error, and if so, did the
problem persist?)

I suspect a filesystem corruption problem or kernel fs driver bug here.
The above answers may help us pin it down.
