Comment 9 for bug 1864787

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.
