The result is:

Reading package lists... Done
Building dependency tree
Reading state information... Done
mokutil is already the newest version (0.3.0-0ubuntu3).
mokutil set to manually installed.
The following packages were automatically installed and are no longer required:
b43-fwcutter libllvm5.0 libqjson0 quvi
Use 'sudo apt autoremove' to remove them.
0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded.
SecureBoot disabled

The KERNEL version is 4.15.0-29-generic and i'm running MInt 18.3 Cinnamon
