New software has been introduced on Ubuntu 23.10: a new Flutter-based App Center and a Firmware Updater tool, as can be read in Ubuntu Desktop 23.10: Mantic Minotaur deep dive.

However, after upgrading from Ubuntu 23.04 to 23.10, I can't find either of these tools.

How can I get them?

I see this as well. Follow the steps below to fix this for Ubuntu 23.10.

Note: The same commands also work for Ubuntu 24.04 (and most likely future versions). Just replace any reference of ubuntu-23.10 with ubuntu-24.04 (or the version you are using).

  1. Run the following commands:

    snap-store --quit
sudo snap refresh snap-store --channel=latest/stable/ubuntu-23.10

  2. If despite the snap-store --quit this tells you that it cannot do so because it has running apps, something along the lines of:

    error: cannot refresh "snap-store": snap "snap-store" has running apps (ubuntu-software), pids:
       3071

    then run:

    kill -9 3071

    or whatever PID is being shown, then once more:

    sudo snap refresh snap-store --channel=latest/stable/ubuntu-23.10

    That brought the App Center in for me.

  3. On to firmware-updater. On my 23.04 → 23.10 it failed during do-release-upgrade. This was easily remedied by just running that install once more once 23.10/24.04 was installed and had rebooted:

    sudo snap install firmware-updater

  4. Lastly, if you're keen, you can:

    snap list --all

    and then run:

    sudo snap remove SNAP --revision=REVISION

    for each disabled snap.

    Thank you - this worked perfectly. I wonder how many other things are different between new-as-intended intended, and upgraded systems. This is an issue that I hope future versions of the upgrade process will handle better. – user105939 Oct 13 '23 at 14:00
  • System Monitor is another application that is not upgraded. It is still the old one. – Kuppuswamy Oct 15 '23 at 23:26
  • From 23.10 fresh installation I got App Center icon showing only empty white page. After trying to update and refresh snap I received icon of old Ubuntu Software showing available new packages. I placed this old icon into my dock and removed App Center icon from the dock to Applications. Now I wait for update re App Center. – Kapel Oct 16 '23 at 08:17
  • I would recommend snap-store --quit instead of kill -9. Let it exit cleanly, also no need to look up PID numbers. – Marius Gedminas Oct 16 '23 at 14:52
  • Isn't plasma-systemmonitor for Kubuntu? – wolfmanFP Oct 27 '23 at 15:21
  • I am not quite sure tbh, but yes that makes sense. If it's not that, what would the "new system monitor" be? Just a misunderstanding? – Thorsten Behrens Oct 28 '23 at 19:52
  • Somehow this did not work for me; 24.10 is still runing snap-store 41.3-72-g80e7130 1216 latest/stable/… canonical✓ - And this happens if I try to run the command again: $ sudo snap refresh snap-store --channel=latest/stable/ubuntu-23.10 snap "snap-store" has no available updates – user105939 Oct 22 '24 at 20:15
  • my was failing due to having both versions installed . uninstall failed due to directory-not-empty - removed manually, uninstalled, then installed – user105939 Oct 22 '24 at 21:26
