A.3 Creating a Local Mirror of the NVIDIA
and Canonical Repositories
The procedure below describes how to download all the necessary packages to create a
mirror of the repositories that are needed to update NVIDIA DGX A100 systems. For more
information on DGX OS versions and the release notes available, go to DGX OS Server
Releases .
Note : These procedures apply only to upgrades within the same major release, such as
4.x → 4.y. It does not support upgrades across major releases, such as 3.x → 4.x.
1.
Identify the sources corresponding to the public NVIDIA and Canonical repositories that
provide updates to the DGX software.
You can identify these sources from the /etc/apt/sources.list file and the contents of /etc/
apt.sources.list.d/ directory, or by using System Settings, Software & Updates.
2.
Create and maintain a private mirror of the repository sources that you identified in the
previous step.

If you are running DGX OS 4.x, see Creating the Mirror in a DGX OS 4 System.
•
If you are running DGX OS 5, see Creating the Mirror in a DGX OS 5 System.
3.
Update the sources that provide updates to the DGX system to use your private repository
mirror instead of the public repositories.
For detailed instructions, see , which provides examples for DGX OS Desktop 4 releases.
To update these sources, modify the /etc/apt/sources.list file and the contents of /etc/
apt.sources.list.d/ directory.

A.3.1 Creating the Mirror for the DGX OS 4 System
The instructions in this section are to be performed on a system with network access.
Prerequisites

A system installed with Ubuntu OS is needed to create the mirror because there are
several Ubuntu tools that need to be used.

You must be logged in to the system installed with Ubuntu OS as an administrator user
because this procedure requires sudo privileges.

The system must contain enough storage space to replicate the repositories to a
filesystem; the space requirement could be as high as 250GB.
