A SUSE operating system release is considered "supported" if the vendor continues to provide security patches for the product. With an unsupported release, it will not be possible to resolve security issues discovered in the system software.

# cat /etc/os-release
NAME="SLES"
VERSION="12"

Fix

If the system requires Long-Term Service Pack Support (LTSS), obtain the correct LTSS subscription for the system.
