[Bug 1879286] Re: [UBUNTU 20.04] Netplan configuration fails to apply in subiquity installer

[Frank Heimes]

Thx for the hint, Michael. I now tried again based on the current daily-
live image - plain as well as with edge enabled - and I got autoinstall
to work on a z/VM (means with real ccw devices).

The only difference between current daily and edge is that edge is a bit
nicer (afaics) if one tries to login while the install is running. The
edge version gives some hints to hit Enter and allows that from remote.

For reference here are my settings:

parmfile / kernel args:

As one can see I enabled one qeth network device and one DASD disk
manually via early-commands.

So I can confirm that it's working with the current focal daily-live
image (or newer).

  [UBUNTU 20.04] Netplan configuration fails to apply in subiquity
  installer

Status in Ubuntu on IBM z Systems:
  Confirmed
Status in subiquity package in Ubuntu:
  Confirmed

Bug description:
  I'm installing Ubuntu 20.04 with a nocloud-net installation source on
  a z/VM guest. I'm currently limited to seeing installation output only
  through webhook reporter, because I cannot access shell on the target
  system during installation.

  Configuration seems to be working fine when applied on a manually
  installed system.
