Giving password configuration as Yes in SSHD Config file ended up throwing an error

Question

I installed ubuntu on vagrant and gave password configuration as Yes in SSHD_Config file but it ended up throwing the following error.

Where am I going wrong?

Answer 1

It looks like somehow your config file of OpenSSH-server got corrupted, please remove and try to install it once more and check if you can start the service or not?

sudo apt-get purge openssh-server
sudo apt-get install openssh-server

If you are using centos:

yum remove openssh-server
yum erase openssh-server
yum install openssh-server
