What option was there then? How was the disk partitioned (or not) ahead of time?

Hi Walter
I ran into this problem on two different machines, one with an SSD HDD and one with a regular HDD. Both machines had Lubuntu 18.04.01 installed.

I also had the same problem today, where I installed lubuntu-18.10-beta-desktop-amd64. I did a manual partitioning and the installation completed.

I then ran a new install and this the option to select "Erase disk" was suddenly available. So it looks like the bug is related to the current install?

Regards
Henrik

According to the code, the one thing that will inhibit the showing of the option is if something is mounted.

Hi Walter
I think we can close this one.

I installed the latest build, as of yesterday, and I no longer experience this problem.

Regards
Henrik

At least for now, I can't see of a great solution to the problem but I think I understand what it is. The option is not provided, as I said, if anything is mounted. Well, a feature of all of the Ubuntu images is that they automount swaps in an attempt to increase available memory. The solution is to `swapoff` those before running the installer. There's been a discussion about unmounting everything, or at least swaps, but even both of those are contentious issues. Still, I made a comment on an upstream bug. We'll see what happens.
