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 systems. The steps are
specific to versions 4.0.X and 4.1.X, but they can be edited to work with other versions.
For more information on DGX OS versions and the release notes available, visit https://
docs.nvidia.com/dgx/dgx-os-server-release-notes/index.html#dgx-os-release-number-
scheme. For more information on how to upgrade from versions 4.0.x to 4.1.x, review the
release notes: https://docs.nvidia.com/dgx/pdf/DGX-OS-server-4.1-relnotes-update-guide.pdf.
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.
A.3.1. Creating the Mirror in a DGX OS 4 System
The instructions in this section are to be performed on a system with network access.
Here are the 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 file
system. The space requirement could be as high as 250 GB.
‣
An efficient way to move large amount of data is needed, for example, shared storage in a
DMZ, or portable USB drives that can be brought into the air-gapped area.
The data will need to be moved to the systems that need to be updated. Make sure that any
portable drives are formatted using ext4 or FAT32.
1. Make sure the storage device is attached to the system with network access and identify
the mount point of the device.
Example mount point used in these instructions: /media/usb/repository
2. Install the apt-mirror package.
$ sudo apt update
$ sudo apt install apt-mirror
3. Change the ownership of the target directory to the apt-mirror user in the apt-mirror
group.
$ sudo chown apt-mirror:apt-mirror /media/usb/repository
The target directory must be owned by the user apt-mirror or the replication will not
work.
