This simple tutorial shows how to install PPSSPP for playing PSP games on Ubuntu 18.04, Ubuntu 20.04, Ubuntu 22.04, and their based systems, e.g, Linux Mint 20/21 and Zorin OS 17.

PPSSPP is a free open-source PSP emulator for Windows, macOS, Linux, and mobile devices including iPhone, Android, Nintendo WiiU, Nintendo Switch, BlackBerry 10, MeeGo, Pandora, Xbox and more.

The software keeps updating with new features and bug-fixes. And, now the latest is v1.16.x, that features:

  • RetroAchievements support
  • New JIT backends: RISC-V, based on IR, and x86 JIT based on IR.
  • And many other changes. See the News page for details.

How to Install PPSSPP Emulator in Ubuntu:

The game emulator offers official binary packages at the links below:

For Ubuntu Linux, only third-party Flatpak and Ubuntu PPA packages are available at the moment. And here you may choose one method that you prefer.

Option 1: Install PPSSPP via Flatpak:

Flatpak is an universal Linux package format runs in sandbox. It comes with most dependency libraries bundled, and takes a few hundred MB more disk space than native .deb package from Ubuntu PPA.

The PPSSPP Flatpak supports both modern 64-bit AMD/Intel PC and AArch64 processor, such as Raspberry Pi and Apple Silicon. And the package is maintained and updated timely by the community, consists of Linux developers.

1.) Install Flatpak daemon in Ubuntu:

If you’re first time installing a Flatpak package in Ubuntu, open “terminal” from start menu and run command to install the daemon:

sudo apt install flatpak

NOTE Ubuntu 18.04 users have to add this PPA before installing the daemon.

2.) Add the Flathub repository:

Flathub is the de facto standard for getting Flatpak packages. To add the repository, simply run command:

flatpak remote-add --if-not-exists flathub https://dl.flathub.org/repo/flathub.flatpakrepo

3.) Install PPSSPP Flatpak

After installed the daemon and added the repository, run command to install PPSSPP:

flatpak install flathub org.ppsspp.PPSSPP

Like normal apps, you can finally open PPSSPP by searching from the overview screen. Though, you may need to log out and back in if app icon not visible.

And, to update the Flatpak package, just run command:

flatpak update org.ppsspp.PPSSPP
4.) How to Remove PPSSPP Flatpak package (Optional)

For any reason, you can easily remove the package by running command in terminal:

flatpak uninstall --delete-data org.ppsspp.PPSSPP

And remove unused runtime to free up space via flatpak uninstall --unused.

Option 2: How to Install PPSSPP via Ubuntu PPA

There’s an unofficial PPA that so far contains the latest deb packages for Ubuntu 22.04, Ubuntu 20.04, Ubuntu 18.04 (dropped), and Linux Mint 21/20.

The PPA package now also supports for 64-bit PC/laptop, and arm64/armhf devices, such as Raspberry Pi.

1.) Open terminal either by searching from activities overview or by pressing Ctrl+Alt+T on keyboard. When terminal opens, run command to add the PPA:

sudo add-apt-repository ppa:xuzhen666/ppsspp

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

2.) Then refresh system package cache and install PPSSPP via command:

sudo apt update

sudo apt install ppsspp

You may also install the SDL version via sudo apt install ppsspp-sdl.

Uninstall PPSSPP PPA package:

To remove the PPA, either go to Software & Updates > Other Software, or run command:

sudo add-apt-repository --remove ppa:xuzhen666/ppsspp

To remove the Sony PSP emulator, run command:

sudo apt remove ppsspp ppsspp-sdl

Prefer installing Chromium browser via DEB rather than using SNAP package? Here’s how to install Chromium .deb package in Ubuntu 20.04 via PPA.

Since Ubuntu 20.04, Chromium deb in the main repository is empty!! It will automatically install the containerized snap package when you trying to install it via apt command.

For those prefer deb to the universal snap package format, user may install the browser either from Linux Mint repository or using a third-party Ubuntu PPA.

Option 1: Install Chromium using Linux Mint repository:

Linux Mint, the popular Ubuntu based system now maintains the latest Chromium DEB packages in its repositories since the developers does not like Snap.

I’ve written about how to add the Linux Mint repository and install Chromium step by step in another post.

Option 2: Install Chromium via third-party Ubuntu PPA:

Personally, I prefer the package from Linux Mint a bit more. Though, there’s now a trustworthy third-party PPA maintains the latest Chromium package. And, the PPA supports Ubuntu 16.04, Ubuntu 18.04, Ubuntu 20.04 and Ubuntu 21.04 so far. Ubuntu 21.10 is somehow not supported at the moment.

1. Add the PPA

Firstly, press Ctrl+Alt+T on keyboard to open terminal. When it opens, run command to add the PPA:

sudo add-apt-repository ppa:savoury1/chromium

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

For Ubuntu 20.04 and earlier, the FFmpeg PPA is also required as dependency:

sudo add-apt-repository ppa:savoury1/ffmpeg4

NOTE: Update system ffmpeg library might cause conflict to other packages in your system. It’s NOT recommended for beginners!

2. Update the package cache:

For Ubuntu 18.04 and earlier, user need to manually update the package cache after adding the PPA. To do so, run command in terminal:

sudo apt update

3. Install Chromium package:

Finally, install the Chromium browser package in .deb format via command:

sudo apt install chromium-browser

Keep an eye on terminal output, it should start downloading the package from the PPA. If not, press Ctrl+C on keyboard to stop it.

Once installed, search for and open the browser from ‘Activities‘ overview screen. And, check its version in about page.

Remove Chromium:

To remove the web browser, simply open terminal via Ctrl+Alt+T shorcut key and run command:

sudo apt remove --autoremove chromium-browser

And remove the PPA, use command:

sudo add-apt-repository --remove ppa:savoury1/chromium

For the FFmpeg PPA, it’s recommended to purge it which also downgrade all installed packages:

sudo apt install ppa-purge && sudo ppa-purge ppa:savoury1/ffmpeg4

Without downgrading the packages, you may instead remove the PPA using the previous command.

This simple tutorial shows how to install (and uninstall) FreeFileSync, open-source file synchronization software, and create application shortcut in Ubuntu 20.04  and Ubuntu 22.04 LTS.

3.) The installer starts a terminal window. And, you have to answer ‘y’ to access license terms. Or, press ‘s’ to show details then ‘y’ to accept, or ‘n’ to refuse.

4.) The installer by default to install the software for system wide into /opt/ directory. Meaning, all users in this Ubuntu system can run it.
For choice, you can type 1 to switch to current user only. If you want, also type 2 to change installation directory, and type 3 to choose whether to add the app icon to the desktop.

When done selecting installation type, directory, and whether to create desktop shortcuts, hit Enter to start the process. If everything goes well, it will show you something as the screenshot below, indicates that all done.

5.) Enable desktop icons.
The desktop icons by default are not usable due to permission issue. Just right click on them one by one and select “Allow Launching” will make them work.

Or, simply delete the desktop icons (move to trash) since you can launch FreeFileSync from start menu or Gnome overview (depends on your desktop environment).

How to Uninstall FreeFileSync:

The installation folder contains a uninstall script to remove FreeFileSync from your system.

Press Ctrl+Alt+T on keyboard to open terminal, then run either command below to uninstall:

  • If installed for current user only, then run command:
    $HOME/FreeFileSync/uninstall.sh
  • For all users (if installed system wide), use command:
    /opt/FreeFileSync/uninstall.sh

If you selected non-default installation directory, then replace $HOME/FreeFileSync or /opt/FreeFileSync in the command above according where you installed the software.

In case you forgot where it was installed, use either command below to tell:

cat /usr/share/applications/FreeFileSync.desktop |grep Exec
cat $HOME/.local/share/applications/FreeFileSync.desktop |grep Exec
