[Bug 1933523] Re: Temporary installer password and key fingerprints are not printed with latest impish daily ISOs

[Frank Heimes]

Regarding the (main) s390x ttys:
SCLP line-mode terminal device driver                /dev/sclp_line0   ('Operating Systems Messages')
SCLP full-screen mode VT220 terminal device driver   /dev/ttysclp0     ('Integrated ASCII console', or z/VM)

Subiquity tui can only run in full-screen, not in line-mode.

There are two "consoles" in case of an LPAR - the "Operating Systems Messages" (line-mode) where only low-level console messages are displayed, including the installer boot messages that contain the temporary installer password,
and the "Integrated ASCII Console" (the emulated VT220 full-screen-mode) where the subiquity tui can run - and is in fact started there automatically (this still works and allows to complete an installation).

The z/VM console (by default) uses the 3215 line-mode, for the console
messages that include temporary installer password, but the Subiquity
tui can not run there (since it's line-mode), hence a remote ssh
installation is needed here.

Just notice that all this worked fine in the past - and even with the
early Impish images (about 06-14-2021 and before) and I do not think
that things changed that much.

And since paride tried a current impish amd64 ISO image, where the temp
installer password is also missing,things seems to be platform agnostic
and should not be cause by any of the special s390x consoles - I think.


What's missing is an output like this (see attached example.txt taken from a 20.04 installation), that provides lines like:
"
"Set the following 'random' passwords"
installer:x3Z9hgeXCPNDQC8VFeqK
"
and
"
It is possible to connect to the installer over the network, which
might allow the use of a more capable terminal and can offer more languages
than can be rendered in the Linux console.


To connect, SSH to installer at 10.245.236.14.

You should use the preconfigured password passed to cloud-init.

The host key fingerprints are:

RSA     SHA256:YTmNejNSf1OlzQbOcNzkcYrDzqfy9aoT1laAs+oca5k
ECDSA   SHA256:MKGkFuNzdQ3aNBL33bhqapn8clpDD9ZIL2SLr24IDAI
ED25519 SHA256:NitkBIaBVl97j1E3AXOrQRNrfR89UChEFxbJWnYhtVE
"
and yes, I believe the output came from cloud-init.

And even earlier the random / temp. password was not only given
"somewhere" in the boot log, but also at the end (close to "To connect,
SSH to installer at 10.245.236.14."), so that one didn't needed to scroll
through the messages to find it.

Title:
  Temporary installer password and key fingerprints are not printed with
  latest impish daily ISOs

Bug description:
  Using the latest Impish daily ISO (timestamp) 2021-06-24 I faced the
  situation that I didn't got a temporary installation password not the
  key fingerprints at the end of the installer boot-up process.

  Hence I am not able to perform an installation from remote via ssh.
  However, subiqity is started at the console (e.g. Integrated ASCII console) and an installation can be successfully completed there, but a console installation is not in all cases possible, for example with z/VM guests.

  As one can read between the lines I tried this on s390x (Integrated
  ASCII console and z/VM), but 'paride' tried the same on amd64 and ran
  into the same symptoms, so it does not seem to be architecture
  specific.

  This must have happened recently, since I already was able to do ssh-based Impish installations on s390x in the past (for example with the daily ISO from 06-14-2021).
  ___

  This is not the case for the 20.04 dailies - I can do remote ssh installation with the 20.04 live daily ISOs.
  ___

  With Impish on s390x the kernel parameter 'quiet' is still set by
  default.
