How to Disable Snap on Ubuntu 22.04

Introduction

Snap is Linux package manager (such as apt) with its own package ecosystem and app store, and it’s being pushed as new default on the latest Ubuntu release (22.04 Jammy Jellyfish). On Ubuntu 22.04, a fresh installation brings Firefox installed as Snap, and apt installs snaps when they’re available. This wouldn’t be such a problem if Snaps were as stable as .deb packages. In this specific case of Firefox as snap, imagine that you have just installed the system and you can’t open your browser because Snap is broken. You can’t google your issue and your error messages directly, because the browser is broken. This happened to me on all 5 installations I did of Ubuntu 22.04 in the past few weeks.

I personally believe pushing Snap to users by default is a bad decision from Ubuntu, since there are known stability issues (like it getting broken right after a fresh install, which happened to me) that simply don’t happen with traditional .deb packages. That’s why I decided to remove Snap (all apps and snapd) altogether from my system. After that I was able to install Firefox from the Mozilla team PPA, and things are running smoothly since then (it’s been a couple of weeks).

In this guide, I share how I disabled Snap and purged it from my Ubuntu 22.04 system. That doesn’t mean I hate it, I just don’t want to deal with Snap now. I believe things should improve and maybe we’ll see a more stable platform in the next LTS release. For now, my choice is to remove it.

Disclaimer: Do this at your own risk. Although the procedure described here won’t break your system, you may face limitations in the future (e.g: if a software is only available as Snap, or if you wanted to enable LivePatch).

Requirements

This guide was developed and tested within the following environment:

  • Linux Ubuntu 22.04

Step 1: Disable Snap

Start by disabling the Snap services within Sysctl:

sudo systemctl disable snapd.service
sudo systemctl disable snapd.socket
sudo systemctl disable snapd.seeded.service

Step 2: Remove Snap packages

Next, list your Snap packages to see what is currently installed. You should see Firefox as one of the snaps.

sudo snap list

Then, uninstall the packages. Because some packages depend on each other and there doesn’t seem to be a way to automate the correct order in which they should be removed (also, poor error messages) it is better to remove each one individually. This way you will be notified if a package is a dependency and must be removed last.

sudo snap remove firefox
sudo snap remove snap-store
(…)
Repeat this with all the snap packages in the snap list list.

Step 3: Remove Snap

Next, fully remove Snap from your system with:

sudo apt autoremove --purge snapd

Finally, clear any leftover cache from Snap:

sudo rm -rf /var/cache/snapd/
rm -rf ~/snap

Snap should now be completely removed from your system.

Next Steps

With Snap removed, you’ll need to install Firefox from a PPA. Because apt will still try to install the Snap version of Firefox, you will run into an error. There’s a trick to overcome that issue: pinning Firefox with Apt.

Create a new file within Apt’s preferences dir:

sudo nano /etc/apt/preferences.d/firefox-no-snap

Include the following content in the newly created file:

Package: firefox*
Pin: release o=Ubuntu*
Pin-Priority: -1

Save and exit. With nano, you can do that by typing CTRL+X, then Y and ENTER to confirm.

You can now add Mozilla’s PPA with:

sudo add-apt-repository ppa:mozillateam/ppa

When running the add-apt-repository command, the update happens now automatically, so you don’t need to run sudo apt update anymore.

Install Firefox with:

sudo apt install firefox

So, you should now have a Snap-free Ubuntu with Firefox installed.
