New question #78160 on Ubuntu:
https://answers.launchpad.net/ubuntu/+question/78160

On 9.0.4 I changed the permissions via above command. I regained my root by recovery mode using:
chwon root:root /usr/bin/sudo
and then a 
chmod 4755 /usr/bin/sudo
, but I am noticing anomalies (ubuntu-tweak could not authenticate, which previously could authenticate).

Using File Browser I see that the permissions are not 777 but rather (read write for root, read for group and others and execute as a program) for other files in that directory.

So did the 777 actually work?

Is there a listing of what permissions should be for some of the children folders such as bin and sbin? 

Reinstall is not an option as in I know I will have to deal with what I have.
