I'm on Xubuntu 20.04.6 LTS and want to go to 24.04. My attempt to upgrade was blocked, with this message:
The following packages have been kept back:
fwupd-signed gnome-software gnome-software-common gnome-software-plugin-snap
ubuntu-software
I have no idea how to tell what's keeping them back, let alone how to fix it.
In response to a comment, here's some more detail: the updates are done by a script that records the output in a Journal directory I've created on all of my machines for this purpose. I doubt the details of that process are relevant. What is relevant, perhaps, is this part of the script:
apt-get --quiet upgrade
And this results (in part) with the following output:
The following packages have been kept back:
fwupd-signed gnome-software gnome-software-common gnome-software-plugin-snap ubuntu-software The following packages will be upgraded:

A further comment suggested using apt dist-upgrade but that
just produces:

============
I looked up the 3 not-upgraded packages on synaptic, and I have questions:
- the fwupd package has a comment about Canonical UEFI signing key. Would it be better to just delete the package, or track down how to sign, and if so how?
- the two gnome software packages remind me that this machine came with Ubuntu originally, and I transformed it to Xubuntu. Does that mean I no longer need gnome software at all? Can I just delete them?
