[kwlug-disc] Xubuntu 22.04 to 24.04 Upgrade

[Khalid Baheyeldin]

A followup on the topic at hand (upgrading Xubuntu to 22.04 LTS,
and the snap shenanigans by Canonical).

I had an older test machine which had Xubuntu 20.04, that I upgraded
to 22.04. I got rid of snap when I was on the former, and Canonical did
not force install snap when I upgraded to 22.04.

Things have changed with 24.04, but all is not lost. Read on if you are
interested.

Note that I always use the command line for version upgrades:

sudo do-release-upgrade

During the install, I got a popup saying:

---
Upgrade to the thunderbird snap
Starting in Ubuntu 24.04, all new releases of thunderbird are only
available to Ubuntu users through the snap package.
This package update will transition your system over to the snap by
installing it.
It is recommended to close all open thunderbird windows before proceeding
to the upgrade.
---

The only option is "OK"
So I clicked on that, and the upgrade went smoothly.

After the upgrade, I found that Canonical has installed snap, and some
applications
that are installed using snap. They include Thunderbird, and Firefox.

But it is easy to remove them, and remove snap too:

These are the commands I used:

$ sudo snap remove firefox thunderbird
$ sudo snap remove gnome-42-2204 gtk-common-themes
$ sudo snap remove bare core22
$ sudo snap remove snapd

And don't forget to remove the stub apts that are snap wrappers.

$ sudo apt purge firefox snapd

That is it! No snap.

I then installed the package firefox-esr from the Mozilla Team PPA, and
everyhing
looks normal.
