[Bug 2122583] Re: Current questing daily installation hangs on NW config screen

[Frank Heimes]

Hi Olivier,
I've entered the installer shell right after the zDev screen (which is right before the NW config and could see this:

root at ubuntu-server:/# ip link

network:

    ethernets:
        zz-all-en:
            match:
                name: "en*"
            dhcp4: true
            dhcp6: true
            accept-ra: true
        zz-all-eth:
            match:
                name: "eth*"
            dhcp4: true
            dhcp6: true
            accept-ra: true
root at ubuntu-server:/# cat /etc/netplan/50-cloud-init.yaml
network:
  version: 2
  ethernets:
    enc600:
      addresses:
      - "10.245.236.23/24"
      nameservers:
        addresses:
        - 10.245.236.1
      routes:
      - to: "default"
        via: "10.245.236.1"
root at ubuntu-server:/#

So for the installation session interface enc600 should be active with
static IP - and it seems to be the case, one screen prior to the NW
config.

Then when proceeding to the NW config screen I an stuck again with:

Network configuration                                               [ Help ]

  Configure at least one interface this server can use to talk to other       
  machines, and which preferably provides sufficient access for updates.

I'll check again on LPAR (I might get more details there, since it allows me to proceed with the integrated ASCII console ...)

Title:
  Current questing daily installation hangs on NW config screen

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

Bug description:
  Today I wanted to use the latest questing daily to test an installation with now kernel 6.17 using an interactive install.
  As usual, I've configured static IPs in the basic network setup (casper).
  And when I then reach the "Network configuration" screen, I notice that DHCPv6 is suddenly selected (which was not the case in the past), and I cannot do anything anymore, probably due to the loss of the static IP configuration.
  Due to this I can also not login to the system and save the logs or anything like that.

  Hence I just attach a screenshot ...
