Okay so an update if using LVM and ubuntu 24.04. Run lsblk to figure out where the disk space is, for me this gave me a result like this:

NAME                      MAJ:MIN RM SIZE RO TYPE MOUNTPOINTS
sda                         8:0    0  32G  0 disk
├─sda1                      8:1    0   1M  0 part
├─sda2                      8:2    0   2G  0 part /boot
└─sda3                      8:3    0  30G  0 part
  └─ubuntu--vg-ubuntu--lv 252:0    0  15G  0 lvm  /

1. This tells us a few different things.
2. Your total disk size is 32G (sda).
3. You're using LVM (Logical Volume Management).
4. The LVM partition (sda3) is 30G.
5. The logical volume (ubuntu--vg-ubuntu--lv) is currently only 15G.

To increase the size we'll follow these steps:

Certainly. Here's a succinct outline of the steps in GitHub-flavored markdown format:
markdownCopy# Expand Ubuntu VM Disk Space

Prerequisites

• VM disk size increased in hypervisor
• Ubuntu using LVM
• Using sda3 as the VM disk

Steps

1. Expand the partition:

2. sudo parted /dev/sda
   (parted) print
   (parted) resizepart 3 100%
   (parted) quit

Verify new partition size:

sudo fdisk -l /dev/sda

Resize physical volume:
bash```
sudo pvresize /dev/sda3

Extend logical volume:
```bash
sudo lvextend -l +100%FREE /dev/ubuntu-vg/ubuntu-lv

Resize filesystem:

sudo resize2fs /dev/ubuntu-vg/ubuntu-lv

Verify new size:

df -h

Note
Adjust device names if different (e.g., /dev/sda3, ubuntu-vg, ubuntu-lv).
