When looking for a D7 installer on the NewNet Download Center, you may not find one for the Linux kernel version you have installed (e.g., you have kernel 1160, but the installer is for kernel 957).
For D7 packages, there is no need for an exact kernel match. You can use the closer version available. If, for some reason, you need an installer for a specific kernel version, please create a support ticket specifying the version and why you need it.
When a D7 customer requests to obtain installers for a specific kernel version, you need to escalate the ticket to the Business Unit (BU). The Engineering team will upload the release to the Download Center, enabling the customer to download the installers on their end.
