Upgrading from Ubuntu 20.04 to 24.04

1. Upgrade Ubuntu 20.04 to 24.04

You can upgrade the Ubuntu distribution the Cloudogu EcoSystem is built on just like in any other Ubuntu based system.

2. Adjust apt configuration

After you have upgraded your EcoSystem to Ubuntu 24.04, you have to adapt some of the EcoSystem-specific apt configuration:

  • Adjust the file /etc/apt/sources.list.d/docker.list from 20.04 (focal) to 24.04 (noble)

    • Insert this line: deb [arch=amd64] https://download.docker.com/linux/ubuntu noble stable
    • Remove old lines like deb [arch=amd64] https://download.docker.com/linux/ubuntu focal stable

  • Adjust the file /etc/apt/sources.list.d/hashicorp.list from 20.04 (focal) to 24.04 (noble)

    • Insert this line: deb [signed-by=/usr/share/keyrings/hashicorp-archive-keyring.gpg] https://apt.releases.hashicorp.com noble main
    • Remove old lines like deb [signed-by=/usr/share/keyrings/hashicorp-archive-keyring.gpg] https://apt.releases.hashicorp.com focal main
  • Keep the focal codename in the /etc/apt/sources.list.d/ces.list file.
  • Check your work by running sudo apt update. It should report no errors.

3. Upgrade Docker

Make sure to run at least Docker 20.10, e.g. via sudo docker info | grep Server\ Version. If you are still running Docker 19.03 (or older), you should upgrade, e.g. via sudo apt update && sudo apt upgrade.
