If I create a node using regular node creation I get different kernel and I can successfully upgrade / install linux headers.

How do I get this kind of kernel ? I tried changing the kernel but I couldn't see this kernel, all of them suffixed by linode<nn> like this - 4.9.80-x86_64-linode98, and I coudn't find the linux-headers for them</nn>

I was able to fix it by changing the Image in Build tab of the Nodes.

Thanks!
