Some recommendations of mine what you can do after installing Ubuntu 22.04 LTS “Jammy Jellyfish”.

 

1. Remove Snap

sudo snap remove snap-store core18 snapd
rm -rf ~/snap
sudo rm -rf /snap
sudo rm -rf /var/snap
sudo rm -rf /var/lib/snapd
sudo rm -rf /var/cache/snapd
sudo apt autoremove --purge snapd

Prevent repository packages from triggering the installation of snap

1
sudo gedit /etc/apt/preferences.d/nosnap.pref

# this file forbids snapd from being installed by APT
 
Package: snapd
Pin: release a=*
Pin-Priority: -10

 

2. Install Firefox

Add Mozilla repository.

1
2
sudo add-apt-repository ppa:mozillateam/ppa
sudo apt update

Blocks Firefox installation based on snap packages.
