To start, I can confirm the baseline fail described in the bug report,
exactly as described.

I tested these packages in a way which avoids the bug present in livecd-
rootfs.

First, I did a copy-package including binaries from the proposed pocket
to my PPA: https://launchpad.net/~tsimonq2/+archive/ubuntu/tmp-kubuntu-
srus

After that, I manually built a livefs on Launchpad via the following
Python code:

```
# Import Launchpad and log in
from launchpadlib.launchpad import Launchpad
launchpad = Launchpad.login_with("tsimonq2's livefs creation", "production", version="devel")

# Create the livefs, you must be a member of ~launchpad-livefs-builders to continue
me = launchpad.people["tsimonq2"]
noble = ubuntu.getSeries(name_or_version="noble")
# BE CAREFUL: deleting livefses is currently broken, so double check this:
livefs = launchpad.livefses.new(owner=me, name="kubuntu", distro_series=noble, metadata={"project": "kubuntu", "extra_ppas": ["tsimonq2/tmp-kubuntu-srus"]})
# https://launchpad.net/~tsimonq2/+livefs/ubuntu/noble/kubuntu/ gets created

# Build the livefs
ppa = me.getPPAByName(distribution=ubuntu, name="tmp-kubuntu-srus")
livefs_build = livefs.requestBuild(archive=ppa, distro_arch_series=noble.getDistroArchSeries(archtag="amd64"), pocket="Proposed")
```

That produced the following build:
https://launchpad.net/~tsimonq2/+livefs/ubuntu/noble/kubuntu/+build/742820

Here is the diff between the Noble daily-live manifest and the manifest
produced by that livefs build:

Specifically, you'll notice the packages in question are now installed.

Now, using the latest Kubuntu Noble daily, I created a 10 GB partition
and mounted it at /mnt. I then downloaded the squashfs with the new
packages:

```

And modified the Calamares config to use this new squashfs:

         destination: ""

----------------------

Following this, I went through the incredibly intuitive steps to launch
Calamares and start the Minimal Install. After the install successfully
completed, I rebooted the machine and logged in.

I can indeed confirm that kubuntu-desktop is installed:

$ apt list --installed | grep kubuntu-desktop
kubuntu-desktop/noble,noble-proposed,now 1.451.2 amd64 [installed]

And so is kubuntu-settings-desktop:
$ apt list --installed | grep kubuntu-settings-desktop
kubuntu-settings-desktop/noble,noble,noble-proposed,noble-proposed,now 1:24.04.13 all [installed,automatic]

But not plasma-welcome:
$ apt list --installed | grep plasma-welcome
[ empty output ]

That concludes my testing results. This is probably as close as we're
going to get without a fixed livecd-rootfs.
