[Bug 1768617] Re: Installer fails to remove old partitions

[Diego Reyes]

The iso I used is this one:

0b3490de9839c3918e35f01aa8a05c9ae286fc94 *ubuntu-18.04-live-server-
amd64.iso

I don't remember seeing the option to boot to a live desktop, so I didn't know how to extract any logs.
I could reproduce it with a VM (Virtualbox on ubuntu), but only when installing 18.04 over a 16.04.  If the previous installation was 17.x-desktop, the error didn't show.
I'm attaching a tar with all that's in /var/log, the error I see while installing appears in /var/log/curtin/install.log.
Let me know if I can help.

Title:
  Installer fails to remove old partitions

Status in debian-installer package in Ubuntu:
  New

Bug description:
  When installing Ubuntu 18.04-server over an old installation, after selecting/confirming 'whole disk' the installer fails to remove the old partitions and aborts the process.
  Tested on two different machines both with previous Ubuntu 16.04 installations.
  One workaround is to write zeros to the beginning of the target disk.
