Live session shutdown prompt is missing, just keeps spinning

It appears casper-stop is still running as intended because this appears on tty1 (VT1):

  Please remove the installation medium, then reboot.

So that means /bin/plymouth is executable and was successfully pinged. It just failed to respond to:

  chvt 63
  plymouth message --text="$MSG"

Maybe with the new forking logic we're talking to the wrong instance?

Alright I think I've got a fix/workaround but will wait and see if upstream has a better idea first: https://gitlab.freedesktop.org/plymouth/plymouth/-/issues/152

Here's the fix.

This bug has been reported on the Ubuntu ISO testing tracker.

I'll go ahead and sponsor this as I'd like to see it get tested with the Beta images.

This bug was fixed in the package plymouth - 0.9.5git20210406-0ubuntu2

---------------
plymouth (0.9.5git20210406-0ubuntu2) impish; urgency=medium

  * Add plymouth-switch-root-initramfs-Preload-text-renderin.patch to
    preload all the graphics libraries required by plymouthd before the
    switch occurs. So now casper can render text even from within the
    initramfs regardless of library dependencies (LP: #1942987).

Yes verified fixed in http://cdimage.ubuntu.com/daily-live/20210918/

Tested the Xubuntu Beta release ISO 21-09-2021 on 2 machines and this bug has come alive again.

In comment #9 you verified that it was fixed with "Ubuntu Impish daily" but in comment #11 you are testing "Xubuntu Beta release". Did you previously verify that this was fixed on Xubuntu? I ask as its possible something other than (or in addition to) plymouth is causing the issue on Xubuntu.

@brian-murray

Yes I did verify that it was/is fixed in Ubuntu and it is - I tested Ubuntu again today - and no I never confirmed "officially" that Xubuntu was fixed.

As noted in comment # 11 Xubuntu has the issue - I also just tested Ubuntu Mate's latest ISO 2021-09-21 and the issue is just a bit different - there is no prompt to remove media after clicking the restart button - however the system reboots at once.

Yes I think that something other than plymouth might be causing the problem.

Again this does not occur in Kubuntu,Lubuntu or Ubuntu I have tested all their beta images today.

Please open a new bug report for this issue so we can have a new bug to reference in the changelog of any upload which fixes this, but please also mention this bug report so we do have history. Thanks in advance!

@brian-murray

Ack. Will do in the AM.

New bug report filed as requested -

https://bugs.launchpad.net/ubuntu/+source/casper/+bug/1944519

On Xubuntu, the issue seems to be inconsistent. I've observed two different phenomena:

1. Only the Xubuntu logo is displayed. Nothing else happens.
2. Xubuntu logo, spinner, and message are all correctly displayed.

Using Xubuntu daily 2021-09-21 I got no eject on some tried test boxes

Boxes that ended with plymouth (Xubuntu & logo - no spinner though)
- sony vaio svp112a1cw (i5-9400u, 4gb, intel haswell-ULT)
- dell [optiplex] 755 (c2d-e6850, 5gb, amd/ati radeon rv516/x1300/x1550)
- hp dc7700 (c2d-e6320, 5gb, nvidia quadro nvs 290)

Boxes that ended with black screen & cursor/underscore (static/not-blinking)
- dell [optiplex] 780 (c2q-q9400, 8gb, amd/ati cedar radeon hd 5000/6000/7350/8350)
- hp 8200 elite sff (i5-2400, 8gb, nvidia quadro 600)

Box that ended with just black screen
- lenovo thinkpad x201 (i5-m520, 4gb, i915)

(sorry I missed bdmurray's comment #14 - will comment in other report as well; comment on other report contains other thoughts too)
