Error while installing Lubuntu 19.10... please help


I’m trying to install Lubuntu by erasing my current drive and replacing it with lubuntu 19.10.
I previously was using a 18.04 LTS version which I decided to update.
as soon as I started Lubuntu 19.10 installer and click install I get this error

Installation Failed

The installer failed to create a partition table on lubuntu-vg.

========================================================================================== Create a new partition table (type: msdos) on ‘/dev/lubuntu-vg’ ========================================================================================== ========================================================================================== Job: Create new partition table on device ‘/dev/lubuntu-vg’ ==========================================================================================

My computer specifications:
Processor: intel I3 4000m
Graphics card: intel HD
Ram: 2gb ddr3

Did you check the installation media for defects at the boot screen?

Yes, please check first the checksum of the downloaded ISO.

/dev/lubuntu-vg looks like LVM is in use. As far as I know, you cannot create a partition table inside the volume group (but I might be wrong). And I am not sure, if Calamares can handle LVM correctly (I have never tried it).

Can you please provide the output of:

sudo parted --list

I checked the installation media for defects and there was no problems

here is the
sudo parted --list
Model: ATA WDC WD5000LPVX-2 (scsi)
Disk /dev/sda: 500GB
Sector size (logical/physical): 512B/4096B
Partition Table: msdos
Disk Flags:

Number Start End Size Type File system Flags
1 1049kB 500GB 500GB primary boot, lvm

Warning: The driver descriptor says the physical block size is 2048 bytes, but
Linux says it is 512 bytes.

What partition scheme did you use when installing?

I chose to erase my current data

You just did the Erase Disk option?

I have tried all options

What is the hash of the ISO you have?

I apologize for the wait, here is the hash:

And indeed 761c4603f689b1a109d67bde3f2ca0bcc750ce973ac8c1a8e98ca188bbc3e760 is correct.

I might suggest booting the live media and deleting all the partitions on the drive and then installing.

All done

Thank you very much!!
