How can I install GNU IceCat on a Debian-based system?

Download the latest version from ftp.gnu.org unpack it then create a symlink to run Icecat from the terminal:

wget http://ftp.gnu.org/gnu/gnuzilla/52.6.0/icecat-52.6.0.en-US.gnulinux-x86_64.tar.bz2
tar xvf icecat-52.6.0.en-US.gnulinux-x86_64.tar.bz2
sudo ln -s $PWD/icecat/icecat-bin /usr/bin/icecat
icecat

Using the guix pacakge manager:

$ guix package -i icecat

The binary should be set under /home/$USER/.guix-profile/bin/icecat. (see 3.2 Invoking guix package).Assuming guix is correctly configured and the $USER/.guix-profile/bin is in your $PATH , you can start the browser from the terminal through:

$ icecat

The GNU Guix package manager is a great way to get IceCat on any GNU/Linux distribution. Download and install Guix, then run: guix install icecat.

Guix also has a whole lot of other relatively new versions of software, so can be a great way to install packages such as NodeJS on top of stable versions of Debian.

Sparky and Trisquel already contains the .deb package of icecat.

apt-key adv --fetch-keys https://sparkylinux.org/repo/sparkylinux.gpg.key

echo 'deb http://sparkylinux.org/repo testing main' > /etc/apt/sources.list.d/sparky.list

or

apt-key adv --fetch-keys http://packages.trisquel.info/trisquel/trisquel-archive-signkey.gpg

echo 'deb http://packages.trisquel.info/trisquel/ flidas-updates main' > /etc/apt/sources.list.d/trisquel.list

Notes

• If you wanna use with older distribution, then look at trisquel distro names which is the closest for yours.
• WARNING: This may also update existing packages, install new packages or suggest removing important packages (for example with apt dist-upgrade). Note, though, that it will not automatically remove packages.
