LUBUNTU can not create partitions on my hardsik (dual boot with Windows 10)

[Nayelhy Renteria]

I am trying to install lubuntu on my laptop, i had choose the manual partition option, the replace an empty space option too, but I am still getting this same error (this is from the option "replace partition", but i am getting a similar error message from the "manual partition" too):
El instalador fallo al crear la partición en el disco 'WDC WD3200BEVS-26VAT0'.
========================================================================================== Crear una nueva partición (101,55 GiB, ext4) en «/dev/sda» ========================================================================================== ========================================================================================== Trabajo: Crear nueva partición en el dispositivo «/dev/sda» ========================================================================================== ========================================================================================== Orden: sfdisk --force --append /dev/sda ========================================================================================== No se ha podido añadir la partición «Partición nueva» al dispositivo «/dev/sda». No se ha podido añadir la partición «Partición nueva» al dispositivo «/dev/sda».
The message is on english but basically says "the installer failed when creating the partition on the disc"
I am using a booteable pendrive USB (with Rufus).
-BIOS mode.

Thank you for taking the time to report this issue and helping to make Ubuntu better.

I suggest you read the release notes for Lubuntu 20.04, ie.
https://lubuntu.me/focal-1-released/
or
https://lubuntu.me/focal-released/

You'll find mention of this issue, and a workaround.
I'm going to mark this issue a duplicate.
