I can confirm, that this regression affects 4.18.0-15 as well as
4.15.0-44. After downgrading to 4.18.0-14 terminals start to work again
for me.
This is the relevant log output:
$ journalctl -f

Title:
Upgraded kernel to linux-image-4.18.0-14.15-generic 4.18.20, and
discovered I can no longer log into a local console
Status in linux package in Ubuntu:
Confirmed
Bug description:
When I attempt to log into a local (Getty) console, having entered my
username, the password prompt appears but then the cursor moves to the
next line as I'm typing the password, and the log in times out with a
'Login incorrect' message, then the console prompt loops, displaying
'[machine-name] login', followed by 'Login incorrect', until systemd
restarts the service for that console.
With the previous kernel, i.e. 4.18.0-13.14-generic the login process
works fine.
This wouldn't normally bother me, as I don't tend to use the local
consoles for much, I just noticed it when I wanted to use one to check
that something else was working correctly.
I've currently set my GRUB config to boot the old 4.18.0-13.14-generic
kernel, as a work-around.
