amazon web services – Session Manager Operation not Permitted ( ssm-user )

I’m trying to run the following command on Session Manager terminal

But I’m getting these errors

enter image description here


chmod 0600 ssh_host_ecdsa_key

chmod 0600 ssh_host_rsa_key

chmod 0640 ssh_host_ed25519_key

I tried sudo but getting something like this

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

Current user is ssm-user but is there any way to apply these command using session manager only ?

Note: I’m not using standard ssh using gitbash since the server is currently having issue with ssh port. The only way to access the server is using session manager.
