For installation instructions, refer to

In addition to upgrading to the versions described in this section, performing a package upgrade can update the software component versions, the Ubuntu 24.04 LTS version, and the Ubuntu kernel, depending on when you perform the upgrade.

For information about LTS software versions for related networking components, refer to the Networking Long-Term Support Releases page.

Important

When you upgrade DGX OS, the system will remain on the same GPU driver branch. If your system is currently using driver version 570 or earlier, which is now end of support, manually upgrade the driver to the 580 branch as outlined in Upgrading Your GPU Driver Branch.

Important

This release incorporates the following updates:

  • Ubuntu ConnectX drivers and DOCA-OFED stack.

  • Customers are advised to consider these updates and any effect they might have on their application. For example, some MOFED-dependent applications can be affected.

  • Best practices support upgrading select systems and verifying that your applications are working as expected before you deploy additional systems.
