I expected it to work normal giving me root access to the commands.
It gave me an error message that says"sudoers.so"must be writeable only
by the user and actually it is set up to be read and write for all,that
was my mistake when I ran a chmod 777 for the whole lib directory since
then sudo does not work and now when I try to chmod without sudo it
says,permission denied and when I try with sudo it gives me the error,so
it is a circle I can not get out of.Another problem I have,probably,from
the same origin,is the authentication label that do not show the line
where the password should be inserted and instead it shows an error
message that says something about the /usr/lib/policykit being restored
to its original state.Well this is all I have to say ,for the moment.
Thanks.Please see if you can help me.
