Comment 2 for bug 282498

thanks for your report.

The error is
Setting up mythtv-database (0.21.0+fixes18379-0ubuntu1) ...

 * Starting MySQL database server mysqld

   ...done.

 * Checking for corrupt, not cleanly closed and upgrade needing tables.

Failed to connect to database: Access denied for user 'root'@'localhost' (using password: NO) at -e line 5, <> line 1.

Failed to create database (incorrect admin username/password?)

It's also possible that mysql-server wasn't running. After install

is completed, you will need to make sure mysql-server is running

and that you supplied correct information. Try:

sudo dpkg-reconfigure mythtv-database

Then mythexport fails with
Setting up mythexport (1.0.3-0ubuntu1) ...

Your apache2 configuration is broken, so we're not restarting it for you.

ERROR 1049 (42000): Unknown database 'mythconverg'

dpkg: error processing mythexport (--configure):
