Installing Docker CE on Ubuntu 17.10 Artful Aardvark

As of 20/10/2017, a release file for Ubuntu 17.10 Artful Aardvark is not available on Download Docker.

If you are used to installing Docker to your development machine with get-docker script, that won't work either. So the solution is to install Docker CE from the zesty package.

sudo apt-get update
sudo apt-get install apt-transport-https ca-certificates curl software-properties-common
curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -

Fail2ban Configuration

The default Fail2ban installation comes with two configuration files, /etc/fail2ban/jail.conf and /etc/fail2ban/jail.d/defaults-debian.conf. It is not recommended to modify these files as they may be overwritten when the package is updated.

Fail2ban reads the configuration files in the following order. Each .local file overrides the settings from the .conf file:

• /etc/fail2ban/jail.conf
• /etc/fail2ban/jail.d/*.conf
• /etc/fail2ban/jail.local
• /etc/fail2ban/jail.d/*.local
