   How big is the drive overall?  Is it really only 60G?

   If you're lucky, you can pull that EOL version up to 20.04, then again   
   up to 22.04.  If you're not lucky, then you'll need to pave over   
   everything and start over.

   If you in-place update it, the kernel has the best chance to survive,   
   else you're going to get 5.15(or thereabouts), with an option for the   
   6.2 HWE kernel.
