Possibly of significance... Post a `calamares` failed install, I cannot use KDE Partition Manager to delete the partition & re-create for another test. ie
- Load KDE Partition Manager - delete sda9 and click apply ERROR occurred If however I reboot and perform the same steps in KDE Partition Manager of deleting the sda9 system partition, apply, then re-create partition using space & no errors occur?!! In comment #7 I used a 18.04.4 live session to get around repeated failures to delete & re-create partition in 20.04, however I only get the errors AFTER a failed install; KDE Partition manager does it perfectly if calamares hasn't been run. -- 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/ubuntu/+source/calamares/+bug/1864787/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
