Hi,
I would download the installer/update file/container images from a GUI supported server using a browser and transfer the zip file to the server on which Denodo is installed.
You can refer to the [Installing Updates and Hotfixes](https://community.denodo.com/docs/html/browse/8.0/en/platform/installation/installing_updates_and_hotfixes/installing_updates_and_hotfixes) section of the Denodo Platform Installation Guide to install the updates and[ How to create your own Docker images for Denodo Platform Containers](https://community.denodo.com/kb/en/view/document/How%20to%20create%20your%20own%20Docker%20images%20for%20Denodo%20Platform%20Containers) knowledge article to update the custom docker images.
In order to update docker images, I would ensure to download the latest docker container from the support site as it gets updated with the latest updates.For more information on Denodo Platform Docker containers, refer to the [Denodo Platform Container 8.0 QuickStart Guide](https://community.denodo.com/docs/html/document/8.0/en/Denodo%20Platform%20Container%208.0%20QuickStart%20Guide) .
Hope this helps!
