Lubuntu 20.04.02 Installation Failed

Hello everyone,

I’m having trouble installing Lubuntu 20.04 on a Lubuntu 18.04 machine, choosing Erase Disk option in the installation wizard ( Calamares 3.2.20 )

The text error that appears is : The installer failed to create partition table on HDD_DEVICE_NAME

The Lubuntu ISO version is 20.04.2 x64

Follows the errors image descriptions as attachments

Thanks in advance,

Problem solved using gparted on lubuntu live session.

  1. Leave lubuntu installer
  2. Run gparted , or KDE partition manager in alternative
  3. Delete all existing partitions , apply modifications.
  4. Run lubuntu installer again.

Yeah, on the rare occasion when I’ve had issues with a particular box, my usual steps are

  • reboot (on occasion I’ve had issues with KDE Partition Manager or calamares after a calamares crash)
  • I use KDE Partition Manager, being the Qt equivalent of gparted ; though if you’re familiar with gparted it’ll work too. I delete the troublesome partition(s), and create the format I do want, or whatever partition layout i want, then exit
  • finally restart calamares or the Lubuntu installer (now only selecting the partition(s) I setup in the prior step & opting to use (keep) them).

I’ve been using gparted a lot longer so I know it better, though I’ve found KDE Partition Manager as good (being Qt based; it’s more efficient on resources in modern Lubuntu)

Well done on solving it yourself ! (and sharing the solution so it’ll help others)
