linux-image-generic should already install the associated linux-image-extra package, but the name has been changed to linux-modules-extra. Try this to upgrade to the latest kernel:

sudo apt update sudo apt upgrade sudo apt install --reinstall linux-image-generic 

Then, reboot and try using the following command instead:

sudo apt install linux-modules-extra-$(uname -r) linux-image-extra-virtual 

As @mchid said in the comments,

linux-image-extra-*

packages have been renamed

linux-modules-extra-*
