System & maintenance

Basic Ubuntu system update

Updating OS packages via the panel or SSH — security patches and kernel maintenance.

  1. Via the panel

    System maintenance → Select apt update/upgrade action. The panel runs the task in the background and shows the log.

  2. SSH (manual)

    Take a VM snapshot before upgrading. After upgrade check if a reboot is required.

    sudo apt update
sudo apt upgrade -y
[ -f /var/run/reboot-required ] && cat /var/run/reboot-required
    Tip

    Schedule reboots in a maintenance window — web projects will be briefly unavailable.

  3. Post-update check

    Check service status (Nginx, Apache, PHP-FPM, MariaDB) in the panel or recovery tools.

    sudo /usr/local/uadmin/bin/recovery-stack.sh status

  4. PPA release label change

    If apt upgrade fails due to a PPA Release file label change (e.g. ondrej/php), the panel automatically uses --allow-releaseinfo-change. Manual: sudo apt update --allow-releaseinfo-change && sudo apt upgrade -y.
