How to remove Snap completely without losing Firefox?

  • 772

I am wondering whether or not there is a way to completely remove Snap from Ubuntu 21.10 (Impish Indri) without losing the ability to install Ubuntu's default browser Firefox.

When I just recently updated to the newest Ubuntu release I realized that the installer programmatically reinstalled Snap, although I had manually removed it before. Additionally the installer removed Firefox, which was installed via the repositories, and reinstalled it via snap.

As I don't want snap to be installed on my machines for various reasons, my question is: Is there a safe way to remove it, and to get the Firefox DEB back to the sources?

Is there a PPA? Could I use a source of an Ubuntu flavor additionally, which didn't remove the Firefox Deb from its sources?

apt

    You can combine two measures.

    Start by removing Snap package of Firefox by snap remove firefox --purge.

    Then follow the steps:

    1. prevent Snap installation by purging and pinning it with negative priority:

      sudo apt-get autopurge snapd

cat <<EOF | sudo tee /etc/apt/preferences.d/nosnap.pref
# To prevent repository packages from triggering the installation of Snap,
# this file forbids snapd from being installed by APT.
# For more information: https://linuxmint-user-guide.readthedocs.io/en/latest/snap.html

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

    2. Then install Firefox from

      • official repositories as simple as

        sudo apt-get install firefox

        Update april 2022: This option is not anymore applicable in Ubuntu 22.04 and up. Installing the .deb package causes installation of the snap version.

      • some third-party (but trusted) repositories

        a. deb-packaged Firefox from UbuntuZilla - regular or ESR
        Add UbuntuZilla repository with its signing key by

        echo "deb http://downloads.sourceforge.net/project/ubuntuzilla/mozilla/apt all main" | sudo tee -a /etc/apt/sources.list.d/ubuntuzilla.list > /dev/null
sudo apt-key adv --recv-keys --keyserver keyserver.ubuntu.com 2667CA5C
sudo apt-get update
sudo apt-get install firefox-mozilla-build

        Note: if one needs ESR version - then replace last command with sudo apt-get install firefox-esr-mozilla-build.

        Removal is possible by the following commands:

        sudo rm /etc/apt/sources.list.d/ubuntuzilla.list
sudo apt-get autoremove --purge '*firefox*'
sudo apt-get update

        b. deb packaged Firefox ESR version from Mozilla Team PPA

        To get Firefox ESR version installed from Mozilla Team PPA use commands below:

        sudo add-apt-repository ppa:mozillateam/ppa
sudo apt-get update
sudo apt-get install firefox-esr

        Additional locales may be installed by using packages like firefox-esr-locale-it (example for Italian).

        To remove deb-packaged Firefox one can use commands like:

        sudo apt-get install ppa-purge
sudo ppa-purge ppa:mozillateam/ppa
sudo apt-get autoremove --purge

      • Locally extracted Firefox archive

        If one needs to download and install Firefox to the home folder, then it is possible in the following way:

        mkdir ~/Software ~/bin
cd ~/Software
wget -c http://ftp.mozilla.org/pub/firefox/releases/93.0/linux-x86_64/en-US/firefox-93.0.tar.bz2
tar -xf firefox-93.0.tar.bz2
ln -sf /home/$USER/Software/firefox/firefox ~/bin/firefox

# create desktop-file with long command below
mkdir -p ~/.local/share/applications/
cat <<EOF >  ~/.local/share/applications/firefox-user.desktop
#!/usr/bin/env xdg-open
[Desktop Entry]
Encoding=UTF-8
Name=Firefox (local)
GenericName=Browser
Comment=Web Browser
Exec=firefox %u
Icon=/home/$USER/Software/firefox/browser/chrome/icons/default/default48.png
Terminal=false
X-MultipleArgs=false
StartupWMClass=Firefox
Type=Application
Categories=Network;WebBrowser;
MimeType=text/html;text/xml;application/xhtml+xml;application/xml;application/rss+xml;application/rdf+xml;image/gif;image/jpeg;image/png;x-scheme-handler/http;x-scheme-handler/https;x-scheme-handler/ftp;x-scheme-handler/chrome;video/webm;application/x-xpinstall;
EOF

update-menus

        then logout and login back.

        To remove such local installation use commands below:

        rm -rf ~/Software/firefox
rm -v ~/.local/share/applications/firefox-user.desktop
rm -v ~/bin/firefox
update-menus

    Discussion and notes:

    My personal choice will be one of deb-based.
    I would prefer ESR (2b) to get my Firefox behavior stable as it is needed for enterprise level application.

  2. You can download the latest official .deb builds for Ubuntu 22.04 LTS (Jammy) here: https://launchpad.net/~phd/+archive/ubuntu/firefox/

    This is a PPA repository with official Ubuntu packages released originally for Ubuntu 20.04 LTS (Focal) and updated automatically as soon as a new version is released.

    Remember to backup your ~/.mozilla directory (or the snap equivalent).
