Open Update Manager (it's in your mint menu, you can also open it by clicking the grey shield icon on your panel (taskbar))

In Update Manager in the menu bar click View >> Linux Kernels

You'll see something like this:

In the left column, choose whichever kernel version you wish to install (if you were told to upgrade kernel in #linuxmint-help, you'll want to install kernel 5.0 most likely,
In the right column, choose the highest number available

Click Install and wait for the installation to complete
IMPORTANT NOTICE:
If you do experience problems while booting, hold down left SHIFT key while booting to enter the GRUB menu, here you can choose to boot from your previously working kernel. (letter E for advanced boot options)

It is highly advised to always keep at least 1 kernel that you know was working on top of the kernel you're currently using, so that if you ever run into issues, you can go back to a previous kernel that you knew worked.
In order to activate the new kernel, you'll have to reboot.
