How to migrate your Auvik Collector from Ubuntu 18.04 to Ubuntu 20.04

Follow

Disclaimer: Auvik has provided these instructions for a manual install to Ubuntu version 20.04. This method may work with Ubuntu version 22.04 but has not been approved by Auvik yet. Using a scripted installer may create different steps than those outlined below. Please take this into consideration when attempting this upgrade.

  1. Connect to the OVA running your collector, via SSH or by connecting to the VM server running the OVA and launch a bash shell instance (option 6 in the agent-console menu).

    1. Ensure the VM is up to date with the latest software versions for installed packages.
      1. Update APT package caches: sudo apt update

Note: It is recommended that you reboot the VM at this point to ensure any package upgrades take effect. This can be done by issuing the following command: sudo reboot

      1. Print current releases version information using: lsb_release -a
        auvik:/# lsb_release -a
        lsb_release -a
        No LSB modules are available.
        Distributor ID: Ubuntu
        Description: Ubuntu 18.04.6 LTS
        Release: 18.04
        Codename: bionic
      2. Run the release upgrade command: do-release-upgrade --allow-third-party
      3. If prompted, press 'y' to begin the release upgrade. The output indicates how much room is approximately needed in order to proceed.

      6. During the installation, you may be prompted to configure grub-pc. Select ‘ok’ with the enter key. This will bring you to a menu with multiple options, use the ‘arrow keys’ to navigate up and down the list, and the ‘space bar’ to select ‘/dev/sda’. Once selected (denoted by the ‘*') press ‘tab’ to jump to the ‘<Ok>’ button, and press ‘enter’ to confirm selection.

      7. During installation of various packages, you may be ask to select a configuration to use, select the ‘install the package maintainer’s version' option, using the arrow-keys for navigation and space-bar to select the option. Use tab to jump to the '<Ok>' button, and press enter to accept selection.

      8. Once all packages are upgraded, the process will then prompt for cleaning up of any obsolete packages currently installed, that are no longer needed. Enter 'y' to continue with the cleanup process.

      9. Once the obsolete packages are removed, you will be prompted to reboot the system. Enter 'y' to continue with the reboot process.

      10. Once the OVA has rebooted, we can confirm the new release has been applied using:
        lsb_release -a

        auvik:/# lsb_release -a
        lsb_release -a
        No LSB modules are available.
        Distributor ID: Ubuntu
        Description: Ubuntu 20.04.5 LTS
        Release: 20.04
        Codename: focal

 

Please then validate your collector is online in your Auvik tenant.
