BUG: Ubuntu Server 18.04.1 LTS tty1 "Login Incorrect"
Userspace break as a result of missing patch backport

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?

Ur solution (2) would work fine, but consider using ssh meanwhile if you need canonical live patching, i would rather stay at 4.15.0-45, it should be fixed pretty soon:

If you configured FileZilla with sftp, ssh will most likely work with PuTTY, use same port and credentials.

I used the following commands in this order:

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

sudo apt-mark hold linux-*-4.15.0-4[45]-generic

sudo apt remove linux-*-4.15.0-4[45]-generic

I then reboot and uname -a confirmed the default kernel is linux-4.15.0-43-generic
