I had the same problem. I got message: Job: Create new partition on device '/dev/sda' Command: sfdisk --force --append /dev/sda Failed to add partition ...
Both Lubuntu installer and KDE Partition Manager failed to create partition. I tried gparted - it worked fine. So I used gparted first to create a partition and selected that partition in Lubuntu installer. Unfortunately, the installer deleted and tried to re-create the partition, failing again. So once more, I used gparted to create a partition and in the Lubuntu installer I used "Manual partitioning", avoiding partition changes. Finally it worked. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1864787 Title: Lubuntu failed install "sfdisk --force --append /dev/sda" To manage notifications about this bug go to: https://bugs.launchpad.net/calamares/+bug/1864787/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
