Yesterday, I ran some commands to restore permissions of my files on my Centos 6.5, 64 bit system.
I had mistakenly typed chmod -R +w 777. So I needed to restore permissions or reinstall the system.
It seemed to work. The commands can be found here.
I got through it and ran both lines of commands. It works, I am not sure how, but it works.
Now when I came in the morning and typed
sudo yum update
sudo:effective uid is not 0, is sudo installed setuid root?
I am wondering how to fix this.
Any help appreciated. Thanks in advance.
