`run build` fails to fetch Vulkan SDK sources

[tbirdso]

Overview

Building the Holoscan SDK container with run build or directly from Dockerfile fails to pull Vulkan SDK packages.

Details

Holoscan SDK v2.2 and earlier attempts to fetch Vulkan v1.23.216.0 sources directly from lunarg.com when creating the container with Holoscan SDK build dependencies. This step was necessary for early Holoscan SDK versions where Vulkan Debian packages were not available for download on arm64 platforms.

Vulkan v1.23.216.0 packages were removed from the lunarg.com download site on July 23rd, 2024. As a result, users attempting to build the Holoscan SDK build container will see an error when retrieving and unzipping the Vulkan SDK archive.

Who is Impacted

This issue impacts developers that are:

• attempting to build Holoscan SDK (or its build container) from source
• using a machine that did not previously cache layers from building the Holoscan SDK build container.

This issue does not impact developers that obtain Holoscan SDK via other binary distribution methods such as NGC.

Steps to Reproduce

cd holoscan-sdk
git checkout <my-tag>
./run build
