ubuntu 20.04 64 dkms

Friends,

I am installing some software ( actually a driver for a card ) i have had some trouble So I have reloaded my os 20.04 64.

Before I try to install again I see this wisdom offred by the readMe.
".. require some additional libraries and packages:

* dkms
* Linux kernel headers/source (for currently running kernel version)

All packages above are included in most modern distributions. Consult your
distributions documentation for more information..."

so my question : do I have dkms ?

in my /usr/src
/usr/src$ ls
linux-headers-5.11.0-27-generic linux-hwe-5.11-headers-5.11.0-27
linux-headers-5.15.0-97-generic linux-hwe-5.15-headers-5.15.0-97

How can I be sure?

and If i do not have it - is
sudo apt -y install dkms
the suggested action?

thanks much

best wishes
