Problem installing mysql server on 18.04

I have installed mysql-server and then run
sudo mysql_secure_installation
which prompts me to enter a root password.

I then run
mysql -u root -p
and get prompted for the pasword but then I get
Access denied for user 'root'@'localhost'

I have gone round a couple of times being ultra careful with the pwd entry
to no avail.  The log below shows a server restart and login attempt and I
can't see anything wrong.

Any suggestions gratefully received.
