Central Server Ubuntu 20.04 to 22.04 In-place Upgrade.

This document describes the steps required for upgrading Central Server host from Ubuntu 20.04 LTS host to Ubuntu 22.04 LTS.  Please read carefully through the whole document before starting the upgrade process. It is assumed that the reader is familiar with the Ubuntu Linux distribution and has experience of Ubuntu release upgrades and the central server is installed using the installation guide and has a local PostgreSQL database.


If upgrading a system that uses a hardware security module: Please verify that the HSM is compatible with Ubuntu 22.04 and check the HSM module documentation for upgrade instructions.

Upgrading Ubuntu 20.04 to 22.04

Stop the central server and prevent it from starting on boot before continuing to the actual upgrade:

systemctl stop xroad-jetty xroad-signer systemctl disable xroad-jetty xroad-signer
  • Install update-manager-core and software-properties-common if not already installed.

  • Make sure the Prompt line in /etc/update-manager/release-upgrades is set to lts (long-term support)

  • Launch the upgrade tool with the command
    sudo do-release-upgrade

  • Follow the on-screen instructions.

  • When the upgrade is finished, reboot when prompted.

Upgrading the X-Road software

Stand-alone Central Server: Upgrade the database

This step applies only to a stand-alone central server.

  • By default, the Ubuntu upgrade process creates empty database instances that should be removed before the old database is upgraded.

  • List the database instances with pg_lsclusters, and drop the extra ones.
    Do not remove the version 12 (main) running on port 5432
    sudo pg_dropcluster --stop <version, e.g. 14> main

  • Upgrade the old database to version 14:
    sudo pg_upgradecluster 12 main

Update the X-Road package repository to point to the Ubuntu 20.04 packages

  • Update the X-Road apt repository (remove old and add new):

    apt-add-repository -r "deb https://artifactory.niis.org/xroad-release-deb focal-current main" apt-add-repository "deb https://artifactory.niis.org/xroad-release-deb jammy-current main"

    Alternatively, find the repository definition in /etc/apt/sources.list and edit it directly.

Upgrade the packages

sudo apt update && sudo apt full-upgrade

Enable automatic startup and start central server

systemctl enable xroad-jetty xroad-signer
systemctl start xroad-jetty xroad-signer

Verify that the central server services are running and the system is responding

systemctl list-units "xroad-*" "nginx*" "postgresql@*" UNIT LOAD ACTIVE SUB DESCRIPTION nginx.service loaded active running A high performance web server and a reverse proxy server postgresql@14-main.service loaded active running PostgreSQL Cluster 14-main xroad-base.service loaded active exited X-Road initialization xroad-jetty.service loaded active running X-Road Jetty server xroad-signer.service loaded active running X-Road signer

Stand-alone central server only: Drop old database and obsolete packages

After verifying that the database upgrade was successful, drop the old database and remove obsolete PostgreSQL packages.

sudo pg_dropcluster 12 main
sudo apt purge postgresql-12
sudo apt autoremove
