In an attempt to setup the new project, I needed to install nodejs.

Answer 1

Issue: sudo: effective uid is not 0, is sudo installed setuid root?

Noticed: ---s--x--x. 1 dev root 123832 Aug 13 2015 /usr/bin/sudo

user and group should be root and the sudo file should have setuid

Should be ---s--x--x. 1 root root 123832 Aug 13 2015 /usr/bin/sudo

If anyone is still experiencing problems with sudo, I was able t solve it by checking the shell access of the account in WHM. I received the same error because the account had Jailed Shell restrictions. I set it to normal shell and the error was gone.

Answer 3

The problem is that you probably changed permissions to the directory /usr/bin.

To resolve that :

1) First be sure that root is owner of this directory /usr/bin :

chown root:root /usr/bin

2) and change permission for this directory :

chmod u+s /usr/bin/sudo
