Disabling Snaps in Ubuntu 20.04
Don't get me wrong, snaps are great in theory - If you aren't familiar, a snap package is like a sandboxed application that is packaged in such a way that:
- You can be sure you're running exactly what the app developer intended, as all dependencies and assets are bundled into the snap application package
- The snap application generally doesn't own your entire system, it runs in an application sandbox of sorts
- Snaps are cross-platform and distributed independently from apt/deb packages, and as such are usually more up to date than those found in apt
Now this all sounds great, and it is in some ways (especially for app developers), but it comes at a cost: and that is generally performance and annoyances with application theming, access to user folders, and the like. I personally find that if I want to run a sandboxed application I lean more toward Flatpak as it is more performant and seems a bit more mature than Canonical's snap system.
In any event, I usually disable snaps entirely on a fresh install of Ubuntu, and I'll show you how to do that in the new Ubuntu 20.04 release.
1. Remove existing Snaps
On a fresh Ubuntu install, a few snaps come preinstalled. You can see the list of them using
kevin@olubuntu:~$ snap list Name Version Rev Tracking Publisher Notes core 16-2.44.1 8935 latest/stable canonical✓ core core18 20200311 1705 latest/stable canonical✓ base gnome-3-34-1804 0+git.2c86692 24 latest/stable/… canonical✓ - gtk-common-themes 0.1-30-gd41a42a 1502 latest/stable/… canonical✓ - snap-store 20200415.e028804 394 latest/stable/… canonical✓ -
To remove these, you will need them using
sudo snap remove <package>.
Run the following command to remove them all:
sudo snap remove snap-store sudo snap remove gtk-common-themes sudo snap remove gnome-3-34-1804 sudo snap remove core18
You might be wondering why I didn't remove the
core snap...well it turns out you can't remove that one but it will get removed anyway in the next steps.
2. Unmount the snap core service
You'll need to replace the
xxxx with the actual ID inside the
core directory on your system, which you can find out by running
sudo umount /snap/core/xxxx
3. Remove and purge the snapd package
Next, to remove the snapd package and all of its related services, run:
sudo apt purge snapd
4. Remove any lingering snap directories
Finally, you can remove the remaining snap directories on the system. You may not have any of these directories after step 3, and that's okay. I didn't have these directories on a fresh Ubuntu 20.04 install once snapd was removed, but your mileage may vary.
rm -rf ~/snap sudo rm -rf /snap sudo rm -rf /var/snap sudo rm -rf /var/lib/snapd
Enjoy a snap-free Ubuntu
It's that simple, now your Ubuntu 20.04 system is free of Snaps! 🙂
