BUG: Ubuntu Server 18.04.1 LTS tty1 "Login Incorrect"  

[Userspace break as a result of missing patch backport](https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1813873)

As I understand the bug: upgrading the kernel has introduced a bug which has made it impossible to enter a password and log in.

Solutions: 

1. Move back to previous kernel: 

```
sudo apt install linux-{image,headers,modules,modules-extra}-4.15.0-43-generic

```
2. Move forward to kernel 4.18.0-15-generic using Linux commands.

Problem: How can I access my home Web Server when I am unable to log in to the terminal screen? I can manage Linux files using FileZilla on a Windows PC but have not set up sshd (PUTTY) to run Linux commands.

Any suggestions please?
