Install Debian Buster 

Install the 64-bit version of Debian on each machine that hosts one or more of the components.

To install Debian Buster:

  1. To install Debian Buster, see Debian Installation documentation for details.

  2. After the system is installed, make sure that it’s up to date with the most recent security patches. Open a terminal window and issue the following commands as root:

apt-get update

apt-get upgrade

  1. Install sudo and curl for use later in the installation: apt-get install sudo curl gnupg.

  2. Add your username to the sudo group. In the following command, replace {username} with your own username: usermod -a -G sudo {username}.

Now that the system is up to date and your user is in the sudo group, you can start installing the components that make up a Mattermost system.
