Docker Installation Failed

If the Coolify install script fails at the “Installing Docker” step, it’s most often due to the server running a non-LTS version of the operating system — especially common on Ubuntu systems.

Symptoms

Coolify install script fails with an error like:

ERROR: '27.0' not found amongst apt-cache madison results

Solution

• Manually Install Docker
  • Follow the official Docker installation guide to manually install Docker (version 24+)

OR

• Use an LTS Version of Your OS
  • Switch to a Long-Term Support (LTS) version of your operating system, such as Ubuntu 22.04 LTS or Debian 12
