Answer 1

Here is an issue on Drupal Groups: http://groups.drupal.org/node/96639.

Possible solutions:

• Check if your system is Ubuntu (the installation script assumes that it is)
• Remove everything in /var/aegir and run the installation script again.
• Run 'mysql_secure_installation' command and finish it successfully. Aegir checks for security flaws during installation and block it if, for example, you have anonymous users enabled in mysql.
