I'm a beginner in Ubuntu. I had a RDP connection to connect from my Windows10 to a VM with Ubutnu server v. 16.04.5

I launched an upgrade to ubuntu 18 using these commands: sudo apt update sudo apt upgrade sudo apt dist-upgrade sudo do-release-upgrade

The system made its upgrade, and then closed automatically my RDP connection. Since then, I could not re-connect with my IP address.

This is the error message on RDP

and here the error message on Puttty

I read in some links on askubuntu suggesting some commands related to ssh. The issue is that I currently have no access to the ubuntu server to make any of these commands.

Any help please ?

This solution worked for me:

  1. edit sshd_config:

    sudo nano /etc/ssh/sshd_config

change PasswordAuthentication and ChallengeResponseAuthentication to yes.

  1. restart ssh:

    /etc/init.d/ssh restart
