18.04 Subiquity install crashes w/ "no such device" aganist /dev/sda2

[Woodrow Hill]

Downloaded "ubuntu-18.04-live-server-amd64.iso" via Windows, burned with Etcher onto 2 drives (USB 3.0 and USB 2.0). Installing onto a laptop that already had a Debian 9.4.0 install that used the entire disk w/LVM managing partitioning, all partitioning per Debian defaults.

With both drives, I start install, get to the Account Creation stage, and it throws error around failing to run the "removing previous storage devices" and "curtin command block-meta" commands. The Python trackback ends with "no such device or address '/dev/sda2'"

USB drives on this system are clearly working as they not only got install to this point, but a rebuild w/the now-alternative installer (ubuntu-18.04-server-amd64.iso) succeeds.

I think we fixed a bug like this recently but with your description it's a bit hard to be sure. Can you try the ISO at http://cdimage.ubuntu.com/ubuntu-server/bionic/daily-live/current/bionic-live-server-amd64.iso and see if that helps? If it doesn't, can you pastebin the logs in /var/log/installer from the live session?

Hi Michael -- I will try early next week; I have to head out of town tomorrow so re-installing's going to be delayed.

Thanks for the input!

The underlying curtin bug was resolved here:

https://git.launchpad.net/curtin/commit/?id=4bf7750b6010f0483b22ff626eab58d6a85bb072

That's been released in Xenial through Cosmic

curtin | 18.1-17-gae48e86f-0ubuntu1~16.04.1 | xenial-updates

I can't tell what version of curtin gets packaged, the iso manifest doesn't list subiquity either I assume because it's a snap.

I can confirm that the current ubuntu-18.04-server-amd64.iso file available at http://releases.ubuntu.com/releases/18.04/ is still having this problem.

I downloaded it just now and am still seeing the same issue. Will try the daily live image posted above and confirm back

Can confirm the daily image from http://cdimage.ubuntu.com/ubuntu-server/bionic/daily-live/current/bionic-live-server-amd64.iso works fine.
