Error on arm64 while running autoinstaller

[Alfonso Sanchez-Beato]

I am installing on an arm64 server using the autoinstaller, with command line:

linux /vmlinuz console=hvc0 console=ttyAMA0 earlycon=pl011,0x01000000 fixrtc ip=dhcp url=http://192.168.100.1/tftp/bluefield.iso autoinstall ds="nocloud-net;s=http://192.168.100.1/tftp/" cloud-config-url=/dev/null

meta-data is an empty file, while user-data has content:

#cloud-config
autoinstall:
  version: 1
  # ubuntu/ubuntu
  identity:
    hostname: mynic
    username: ubuntu
    password: "$6$rounds=4096$PCrfo.ggdf4ubP$REjyaoY2tUWH2vjFJjvLs3rDxVTszGR9P7mhH9sHb2MsELfc53uV/v15jDDOJU/9WInfjjTKJPlD5URhX5Mix0"
  ssh:
    allow-pw: true
    authorized-keys:
      - "ssh-rsa AAAAB3Nz..."
    install-server: true

The error I see on the console is:

connecting...

and things do not move forward. How I could get the error log in this case?

I am also hitting this error. I believe that this line is the problem:

https://github.com/canonical/subiquity/blob/main/subiquity/server/controllers/network.py#L259

I believe instead of

super().apply_error()

it should be:

super().apply_error(stage)

Yes you're completely right that that is the problem: https://github.com/canonical/subiquity/pull/945

However, this is a crash reporting the failure of something that really shouldn't be failing (probably calling netplan apply, although it could be some other less likely things). So let's fix this and get on to debugging the next problem I guess!

[Michael Hudson-Doyle (mwhudson)]

(does an interactive install work on this system?)

[Michael Hudson-Doyle (mwhudson)]

This should be fixed in edge now.

[Alfonso Sanchez-Beato (alfonsosanchezbeato)]

Thanks, will give it a try! Yeah, interactive installation worked for this system.

[Alfonso Sanchez-Beato (alfonsosanchezbeato)]

@Michael, thanks, the installation now moves forward but as you predicted calling netplan apply fails. I have opened LP:#1927695 with more information.

Is there a way to get into the system when this happens? Note that this is a console interface.

No, we don't have a good answer here so let's add one: https://github.com/canonical/subiquity/pull/950

I've pushed builds of this branch to the 'latest/edge/mwhudson-hack' channel if you want to try it out.

[Michael Hudson-Doyle (mwhudson)]

So the change to not crash on netplan apply failure and the change to offer a shell if autoinstall fails are in the current stable release. I'm not sure there's anything else actionable from this bug so I'm going to close it. Feel free to reopen it or file new ones if I've missed something.
