This simply tutorial shows how to install the latest Lollypop, a lightweight modern Gnome music playing application, in Ubuntu 20.04 and Linux Mint 20 via PPA.
“Lollypop features a party mode which will automatically select party-related playlists to play; a full-screen view which lets you visually access the player from your couch thanks to its HiDPI support; and native support for replay gain.”
1.) Open terminal from your system application launcher. When it opens, run command to add the PPA:
sudo add-apt-repository ppa:gnumdk/lollypop
Type user password (no asterisk feedback) when it asks and hit Enter to continue. The PPA so far provides the latest packages for Ubuntu 20.04, Ubuntu 19.10, and an old version for Ubuntu 18.04.
2.) After adding the PPA, either upgrade the player from an existing release via Software Updater:
or run command in terminal to install the software package:
sudo apt install lollypop
Uninstall:

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:
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:
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.

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:
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):
This simple shows how to easily download & install Google web fonts in Ubuntu and other Linux through 3 different applications.
There are quite a few handy applications that can help downloading & installing Google Web Fonts for offline use in Ubuntu. In this tutorial, I’m going to show you 3 of them, including Font Manager, Font Downloader, and TypeCatcher.
Option 1: Font Manager
Font Manager is a free open-source app for GTK Desktop environments. It allows to preview, download & install Google Web Fonts, or install fonts from local files.
The app works in 3 different modes: Manage, Browse, and Compare. Which can be switched by clicking to top-left button.
While “Manage” mode allows to install, uninstall, preview fonts, “Browse” mode allows you to preview all installed fonts in different categories. As well, it provides option to compare selected fonts (from all installed) side by side.
It as well has command line options, to list, enable, disable, and install fonts in terminal or console.
Besides that, Font Manager also includes extra features, including:
Change system fonts.
Active/De-active installed fonts.
Import/Export.
Add custom user actions.
And more.
Install Font Manager
Font Manager is available in most Linux repositories.
Ubuntu users can simply search for and install it from either Ubuntu Software or App Center. Or, just press Ctrl+Alt+T to open terminal and run command to install:
TypeCatcher is a GTK app designed to search, browse, and download Google webfonts for off-line use. It’s a 12 years old app that’s still working today, though the app rarely gets update now.
The app provides a quite basic UI, allowing to search and browse Google Fonts, preview with selected or custom text in different size. Along with buttons to install, uninstall, and open font URL page in web browser. All the Google fonts are installed to .fonts/typecatcher folder. Just open Files (nautilus file browser) and press Ctrl+H to view them.
Install Typecatcher:
The app is available in Debian and Ubuntu system repositories. User can either open terminal (Ctrl+Alt+T) and run command to install the package:
sudo apt install typecatcher
Or, search for and get it from Ubuntu Software, App Center, or your system package manager.
NOTE: TypeCatcher does NOT launch in Ubuntu 22.04 due to bug, see this step by step tutorial to fix it. In Ubuntu 24.04, it takes quite a few seconds to launch, perhaps due to poor network connection issue.
Option 3: Font Downloader
For choice, Font Downloader is another tool can download & install Google Web Fonts for offline use in Linux Desktops.
The app provides a quite basic user interface, to search, browse, and install fonts! However, I don’t find an option to uninstall.
The only difference to other 2, is that the app provide a button to download font only without install. So, you can use the .tff font files anywhere else.
Get Font Downloader
Ubuntu 24.04 and Debian Sid can get the app simply from system repository, either by running the command below in terminal:
sudo apt install font-downloader
Or, use App Center or system package manager to search & install it as .deb (Debian) package.
For most other Linux, the app is available to install as universal Flatpak package.
(Optional) Change Fonts in Ubuntu Desktop
To change your system fonts in Ubuntu, Fedora Workstation, and other Linux with GNOME Desktop environment. Simply install GNOME Tweaks from system package manager.
Then, you can easily change the font of Interface text, Document text, and Monospace text in the first tab of the app window.
