Solution

You are attempting to extend the root partition using LVM on a system where LVM is not used.

Normally, extending the root partition can be pretty complicated since it's being used, but Ubuntu includes growpart from cloud-guest-utils, so you should be able to do:

growpart /dev/sda 5

This should grow the partition into all available space on the disk as indicated by lsblk, after which you need to run the following to also resize the filesystem:

resize2fs /dev/sda5

Obviously you should snapshot the system first before making any type of changes to disks and partitions as it may break your root partition.
