I need to install MariaDB server in Ubuntu without password prompt. For this purpose, I execute the following commands, but it doesn't gave me any progress. It again shows password prompt.

I used the following commands :

  export DEBIAN_FRONTEND=noninteractive
  echo mariadb-server-5.5 mariadb-server/root_password password mypass | debconf-set-selections
  echo mariadb-server-5.5 mariadb-server/root_password_again password mypass | debconf-set-selections
  sudo apt-get -y install mariadb-server

I also check some links in stack overflow, but it doesnot worked:

Please help me on this regard. Have any wrong with my code?

A mixture of the mysql/mariadb-Nameing has worked for me:

export DEBIAN_FRONTEND=noninteractive
debconf-set-selections <<< 'mariadb-server-5.5 mysql-server/root_password password rootpass'
debconf-set-selections <<< 'mariadb-server-5.5 mysql-server/root_password_again password rootpass'

I believe you just use the mysql commands as it's backwards-compatible:

echo 'mysql-server mysql-server/root_password password test
mysql-server mysql-server/root_password_again password test' > /root/src/debconf.txt
debconf-set-selections /root/src/debconf.txt
