I am using dell 3542, installing the softwares while giving some permission issue as below. I come to know that sudo command is not working. So i have executed 2nd point but no use.
1)
sudo: /usr/lib/sudo/sudoers.so must be only be writable by owner
sudo: fatal error, unable to load plugins
2)
pkexec chmod go-w /usr/lib/sudo/sudoers.so
Error getting authority: Error initializing authority: Error calling StartServiceByName for org.freedesktop.PolicyKit1: GDBus.Error:org.freedesktop.DBus.Error.Spawn.PermissionsInvalid: The permission of the setuid helper is not correct
3) When i exeute ls command it is showing like this
ls -l /usr/lib/sudo/sudoers.so
-rwxrwxrwx 1 root root 185288 Jun 1 2012 /usr/lib/sudo/sudoers.so
How can I fix this issue. Any help is appreciated
