Answer 1

After running the command suggested by @robregonm, I was able to successfully log into the mysql server:

mysql_upgrade -u root -p --force

Need to restart the MySQL server.

Answer 2

mysql_upgrade also works for me:

# mysql_upgrade -u root -p --force
# systemctl restart mysqld

good luck, MSz.
