Remove Ubuntu Snap

This guide shows you how to remove snap packages from an Ubuntu System

Remember to install a browser before removing snaps on a Ubuntu System.

1. View all snaps

   snap list
   

2. Remove snap packages in the following order. Firstly remove Firefox. Secondly, snap-store and the other packages that you see in the above command output in your system.

   sudo snap remove --purge firefox
   sudo snap remove --purge snap-store
   sudo snap remove --purge gnome-*
   

   sudo snap remove --purge gtk-common-themes
   sudo snap remove --purge snapd-desktop-integration
   sudo snap remove --purge bare
   sudo snap remove --purge core*
   sudo snap remove --purge snapd
   

3. Finally, remove the snap daemon via apt command.

   sudo apt remove --autoremove snapd
   sudo nala --autoremove
   

4. So, to stop that, we need to create an apt preference file in /etc/apt/preferences.d and create a new preference file to stop snap.

   sudo -H gedit /etc/apt/preferences.d/nosnap.pref
   

5. And add the following lines, then save the file.

   Package: snapd
   Pin: release a=*
   Pin-Priority: -10
   

6. Returning to the topic, once you save and close the above file, run the below again from the terminal.

   sudo nala update
