Update Instructions

The problem can be corrected by updating your system to the following
package versions:

Ubuntu 24.04 LTS
   linux-image-6.8.0-1025-nvidia-lowlatency  6.8.0-1025.28.1
   linux-image-6.8.0-1025-nvidia-lowlatency-64k  6.8.0-1025.28.1
   linux-image-6.8.0-1026-azure    6.8.0-1026.31
   linux-image-6.8.0-1026-azure-fde  6.8.0-1026.31
   linux-image-azure-fde-lts-24.04  6.8.0-1026.31
   linux-image-azure-lts-24.04     6.8.0-1026.31
   linux-image-nvidia-lowlatency   6.8.0-1025.28.1
   linux-image-nvidia-lowlatency-64k  6.8.0-1025.28.1

Ubuntu 22.04 LTS
   linux-image-6.8.0-1026-azure    6.8.0-1026.31~22.04.1
   linux-image-6.8.0-1026-azure-fde  6.8.0-1026.31~22.04.1
   linux-image-azure               6.8.0-1026.31~22.04.1
   linux-image-azure-fde           6.8.0-1026.31~22.04.1

After a standard system update you need to reboot your computer to make
all the necessary changes.

ATTENTION: Due to an unavoidable ABI change the kernel updates have
been given a new version number, which requires you to recompile and
reinstall all third party kernel modules you might have installed.
Unless you manually uninstalled the standard kernel metapackages
(e.g. linux-generic, linux-generic-lts-RELEASE, linux-virtual,
linux-powerpc), a standard system upgrade will automatically perform
this as well.
