Upgrading from Ubuntu 18.04 to 20.04

1. Upgrade Ubuntu 18.04 to 20.04

You can upgrade the Ubuntu distribution the Cloudogu EcoSystem is built on just like in any other Ubuntu based system. A good reference about the steps to take can be found here: https://www.linuxcloudvps.com/blog/how-to-update-your-server-from-ubuntu-18-04-to-ubuntu-20-04/

2. Adjust apt configuration

After you have upgraded your EcoSystem to Ubuntu 20.04, you have to adapt some of the EcoSystem-specific apt configuration:

  • Adjust the file /etc/apt/sources.list.d/ces.list from 18.04 (bionic) to 20.04 (focal)

    • Insert this line: deb [arch=amd64] https://apt.cloudogu.com/ces/ focal main
    • Remove old lines like deb [arch=amd64] https://apt.cloudogu.com/ces/ bionic main

  • Adjust the file /etc/apt/sources.list.d/docker.list from 18.04 (bionic) to 20.04 (focal)

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

  • Adjust the file /etc/apt/sources.list.d/hashicorp.list from 18.04 (bionic) to 20.04 (focal)

    • Insert this line: deb [arch=amd64] https://apt.releases.hashicorp.com focal main
    • Remove old lines like deb [arch=amd64] https://apt.releases.hashicorp.com bionic main
  • 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.
