If you are getting the following error
“Couldn’t create temporary archive name.”
Check if you are out of disk space.
df -h
After freeing up some space, you should be able to continue increasing the disk size
lvextend -l +100%FREE /dev/redhat/root xfs_growfs /dev/redhat/root
Warning: Be extremely careful when making changes to partitions and disk as it can lead to broken systems and lost data. Make sure you have a backup.
This scenario is done on a basic Ubuntu install. No fancy LVM stuff going on. If you need that, refer to here

From the above output of fdisk -l, we see that the disk has 64GiB available, but the primary partition is only 31G. To make the primary partition larger we need to
You may need to boot up in recovery to get this command working. Also if you boot up in recovery, you’ll need to remount the root / partition read/write. More info here.

Find the thumb drive with lsblk, dmesg, or sudo fdisk -l. In the following examples we are using /dev/sdc1, replace as needed.
sudo cryptsetup --verbose --verify-passphrase luksFormat /dev/sdc1 sudo cryptsetup luksOpen /dev/sdc1 encrypted_usb sudo mkfs.ext4 /dev/mapper/encrypted_usb
Now we can mount the drive. We are mounting it to /mnt change if needed.
sudo mount /dev/mapper/encrypted_usb /mnt
Or go ahead and close the channel and remove the drive
sudo cryptsetup luksClose /dev/mapper/encrypted_usb
sudo cryptsetup --verbose --verify-passphrase luksFormat /dev/sdc1
Wipe /dev/sdc1 and set the password when prompted for it.
sudo cryptsetup luksOpen /dev/sdc1 encrypted_usb
Open up a secure channel to the drive, and decrypt it so we can access it
sudo mkfs.ext4 /dev/mapper/encrypted_usb
Using the channel we created in the previous command, we can now format the drive.
sudo cryptsetup luksClose /dev/mapper/encrypted_usb
We can now close the channel for the drive and remove it.
This is for extending a regular Ubuntu Linux partition, if you need to resize, expand a LVM partition refer to this guide. I am using Gparted as I ran into some issues using parted for moving the partitions around.
Shut the VM down,
sudo shutdown -h now
It is a good idea to take a snapshot of the VM before resizing the disk, so if you run into an issue you have something to revert back to. In the vSphere Client, right click on the VM -> Snapshot -> Take Snapshot.
Change VM Disk size by right clicking on the VM and going to Edit Settings
You can now boot up the VM. Fire up GParted and it should show some unallocated space at the end of your drive.
Now in the next two images we are moving the Extended partition, which contains the Swap Partition to the end of the drive, so the unallocated space is adjacent to our root partition.
Hit Apply and write the changes to the disk then
It should now look like this
Hit apply, then right click on the linux-swap and turn Swapon.
Enjoy the extra space.
