Post aMiSTACX deployments, we recommend patching the Ubuntu OS before you start a new development project or a migration.
In our video, we walk through the steps, and the commands you will need to make use of:
sudo apt-get update
sudo apt-get upgrade
sudo apt autoremove
sudo apt install {packages}
We recommend an AMI backup image before you proceed, and unless you know what you are doing, don’t overwrite any system files; otherwise, the aMiSTACX pre-configured settings will be lost.
Note: If you deployed Magento Open Source with Elasticsearch, then you will also need to remove the Elasticsearch plugins, and re-install the upgrades. You can get the new version from the Elasticsearch logs.
