Last updated: July 19, 2020

Ubuntu 18.04

Ubuntu 19.10 Eoan Ermine reached end of life on July 17 2020. Users are recommended to upgrade to Ubuntu 20.04 LTS.

Ubuntu 19.10 was released 9 months ago, on October 17, 2019. As a non-LTS release, it has 9 months support. Now it is no longer supported by Canonical. No more security and package updates will be accepted to 19.10.

Users are argued to upgrade to Ubuntu 20.04, a LTS release with 5-year support. To get started, do following steps one by one:

Disable third-party repositories by Software & Updates -> Other Software.
Launch Software Updater and install all the updates after checking for updates.
You may restart your computer to complete updates.
Launch Software Updater again, and you’ll see option to upgrade to Ubuntu 20.04

How to Install Pale Moon .deb package in Ubuntu 20.04 & 22.04

Last updated: February 1, 2024

This simple tutorial shows how to install the latest Pale Moon web browser via .deb package and keep up-to-date via Software Updater in Ubuntu 20.04 and Ubuntu 22.04.

Pale Moon is an open-source web browser with an emphasis on customizability. The latest release so far is version 33.0.0 which was released a few days ago and features:

Implement a restricted version of the asynchronous clipboard API (navigator.clipboard).
Add support for SHA-2 (SHA-256/SHA-512/etc.) signatures for OCSP stapled responses.
Add an option to restrict DOM full-screen mode to the existing browser window.
New options (Preference -> Privacy -> Tracking) to allow users to more easily control several privacy-impacting features
Implement PromiseRejectionEvent.

The browser provides official Linux tarball, available to download in its website. The web browser is open-source, but the binary package is NOT. And, I’ve written a step by step tutorial shows how to install the tarball.

How to Install Pale Moon from apt repository:

The opensuse repository offers the most recent .deb packages for Debian and all current Ubuntu releases. It’s open-source but unofficial, and so far supports Ubuntu 18.04, Ubuntu 20.04, Ubuntu 22.04, and Ubuntu 23.10.

Option 1: Download & Install .deb package

First, go to the OBS repository web page via the link button below:

Download PaleMoon (.deb)

For the GTK2 version, go to this page instead. After opening the web page, click Ubuntu logo, select “Grab binary packages directly“, finally you can click download the .deb package for your Ubuntu version and os type.

Don’t know which Ubuntu is running? Press ctrl+alt+t to open terminal, then run lsb_release -a command to tell. Also, run dpkg --print-architecture if you don’t know which one of ‘amd64’ or ‘arm64’ to choose.

After downloaded the package, either click open with “Software & Install” then install, or open terminal (Ctrl+Alt+T) and run command to install it:

sudo apt install ~/Downloads/palemoon*.deb

In case you didn’t save the file in Downloads folder, just type sudo apt install plus a blank space then drag’n’drop the file into terminal instead.

Option 2: Add the repository for receiving updates

To keep the package up-to-date, you may click “Add repository and install manually“, then follow the commands to add the repository into your system.

However, the instruction in that page still works at the moment, but insecure according to new Debian/Ubuntu policy. So, here’s updated commands to do the same job:

1.) First, press Ctrl+Alt+T on keyboard to open terminal. When it opens, copy and paste following single command and hit run to get the key file:

wget -qO - https://download.opensuse.org/repositories/home:stevenpusser:palemoon-GTK3/xUbuntu_$(lsb_release -sr)/Release.key | gpg --dearmor | sudo tee /etc/apt/keyrings/home_stevenpusser_palemoon-GTK3.gpg > /dev/null

NOTE: This command is for Ubuntu (and official flavors, such as KUbuntu, XUbuntu) only. For its based systems, such as Linux Mint, you have to replace $(lsb_release -sr) with 22.04, 20.04, etc, depends on which Ubuntu version your system is based on!

2.) Then run the single command below to create config file & add source repository into it.

sh -c "echo 'deb [signed-by=/etc/apt/keyrings/home_stevenpusser_palemoon-GTK3.gpg] http://download.opensuse.org/repositories/home:/stevenpusser:/palemoon-GTK3/xUbuntu_$(lsb_release -sr)/ /' | sudo tee /etc/apt/sources.list.d/home:stevenpusser:palemoon-GTK3.list"

Also, this command is for Ubuntu (and official flavors) only. For other based system, you need to replace $(lsb_release -sr) with 22.04, 20.04, etc, accordingly.

3.) Finally refresh system package cache by running command:

sudo apt update

The output should include something says “Get : x http://download.opensuse.org/repositories…”, meaning your system is successfully reading packages list from that repository.

Finally, install the web browser via command:

sudo apt install palemoon

You can then use “Software Updater” to receive future updates for this package.

Uninstall:

To remove the web browser, open terminal (Ctrl+Alt+T) and run command:

sudo apt remove --autoremove palemoon

Also, remove the repository by deleting both the source and key files.

sudo rm /etc/apt/sources.list.d/home:stevenpusser:palemoon-GTK3.list

sudo rm /etc/apt/keyrings/home_stevenpusser_palemoon-GTK3.gpg

Finally run sudo apt update to refresh your system package cache.

Python 3.8.4 Released! How to Install in Ubuntu 18.04 / 16.04

Last updated: July 14, 2020

Python 3.8.4 was released a few days ago as the latest stable release of the Python language. Here’s how to install it in Ubuntu 18.04 and Ubuntu 16.04.

This is the first bugfix release that is considerably smaller than the previous three. There’s almost 20% fewer changes at 162 commits than the average of previous three bugfix releases. Detailed information about all changes made in version 3.8.4 specifically can be found in its change log. Note that compared to 3.8.3, version 3.8.4 also contains the changes introduced in 3.8.4rc1.

The deadsnakes team maintains unofficial Python packages for different Ubuntu releases. Note the PPA does not contain Python 3.8 for Ubuntu 20.04 as upstream ubuntu provides the package.

Install Python 3.8.4 in Ubuntu 18.04, 16.04:

1.) Open terminal either by pressing Ctrl+Alt+T on keyboard, or by searching for ‘terminal’ from system application launcher.

When terminal opens, run command to add the PPA:

sudo add-apt-repository ppa:deadsnakes/ppa

Type user password (no asterisk feedback) when it prompts and hit Enter to continue.

2.) Then run commands to refresh system package cache, and install Python 3.8:

sudo apt update

sudo apt install python3.8

3.) Once successfully installed, check your system Python versions (python –version):

4.) (Optional) To use Python 3.8 as the default python3, run commands:

sudo update-alternatives --install /usr/bin/python3 python3 /usr/bin/python3.6 1

sudo update-alternatives --install /usr/bin/python3 python3 /usr/bin/python3.8 2

For Ubuntu 16.04 replace python3.6 with python3.5. And you can then switch between the two Python3 versions via command:

sudo update-alternatives --config python3

NOTE: Due to known bug, terminal won’t open if you changed python3 symlink. An workaround is recreate a symlink via command (For Ubuntu 16.04 replace python3.6 with python3.5):

sudo rm /usr/bin/python3; sudo ln -s python3.6 /usr/bin/python3

Uninstall:

To uninstall the Python3.8 packages, run command:

sudo apt remove --autoremove python3.8 python3.8-minimal

To remove the Deadsnakes PPA, launch Software & Updates and go to Other Software tab, then remove the repository line and close the window.
