Comment 6 for bug 1868249

(Aside: I had selected "update to the latest installer" during installation)

After going to Alt-F2, running parted with "rm 4", "rm 3", "rm 2", "quit", back to Alt-F1 and then selecting "Reset" in Subiquity, this was *almost* enough for it to pick up the updated partition table. It didn't show the deleted partitions any more. However it also didn't show "free space" on that drive so I was unable to create a new partition. Even after a reboot and restarting the installation, "free space" was not available.

In the end, I had to select "Use entire disk", and then modify the automatically-generated partition layout that Subiquity had provided until it matched what I wanted :-(
