recently I have been facing a serious issue on one of my servers. While accessing my server with solar putty on windows I got error accessing the server message on the response. So I tried from my server console but I couldn't access the server. Later I got access with the AWS systems manager with an ssm-agent new user account. But, I can not start or run any service from that user account. It says to use the sudo command but whenever I try sudo the server gives me the following error.
sh-4.2$ sudo yum install polkit
sudo: /etc/sudo.conf is world writable
sudo: /usr/bin/sudo must be owned by uid 0 and have the setuid bit set
and on starting any service the server shows me this
sh-4.2$ systemctl start sshd
Failed to start sshd.service: The name org.freedesktop.PolicyKit1 was not provided by any .service files
See system logs and 'systemctl status sshd.service' for details
What is the issue? I have been trying hard to get the server working. but I am not being able to start the server. Can anyone help me with the issue?
