EE failing to backup database during "ee site update"

I’m trying to run sudo ee site update domain.com --wp --pagespeed and also sudo ee site update domain.com --wp --hhvm

I get the following when I check the logs.

root@domain:/var/www/domain.com# ee site update domain.com --wp --pagespeedEnter your name:

I’ve already checked ~/.my.cnf and the root password in there is the correct mysql root password.

@adrianocorterea

logs infers that you have no .my.cnf file at ~/.my.cnf location so database backup is getting failed
