For those looking for the native .deb package of OpenShot 3.1.0, here’s how to install it from PPA in Ubuntu 18.04, Ubuntu 20.04, Ubuntu 22.04, Ubuntu 22.10, and Ubuntu 23.04.

The official openshot PPA is back with the latest packages for all current Ubuntu releases and their derivatives, such as Linux Mint. User can now easily install the latest video editor package by following the steps below one by one.

Just found that the official openshot PPA seems not being updated for quite a period of time, when I was trying to get the latest package of this video editor today. Though, the software is still being developed.

So I tried building myself and uploaded into this unofficial PPA for those who prefer native .deb package to AppImage or Flatpak.

NOTE this unofficial PPA contains the packages for Ubuntu 22.04, Ubuntu 20.04, and Ubuntu 18.04, though has only minor tests in Ubuntu 22.04.

1. Add the PPA

First, press Ctrl+Alt+T on keyboard to open terminal. When it opens, paste the command below into terminal and hit Enter to add PPA:

sudo add-apt-repository ppa:openshot.developers/ppa

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

2. Refresh package cache

Ubuntu 20.04 and higher will automatically refresh system package cache while adding PPA. Though old Ubuntu 18.04 and Linux Mint do not.

To manually update the cache, run command:

sudo apt update

3. Install/Update OpenShot

Finally, either install the video editor by running command in terminal:

sudo apt install openshot-qt python3-openshot

Or use ‘Software Updater’ to update it from an old version.


To remove the Ubuntu PPA, either open “Software & Updates” and delete the source from ‘Other Software’ tab:

or run the command below in terminal:

sudo add-apt-repository ppa:openshot.developers/ppa

And remove the editor for choice by running command:

sudo apt remove --autoremove openshot-qt python3-openshot

Want to cut a clip out of a video and share with your friends? Try Video Trimmer, a stupid easy way for those working on Linux.

In Linux there are quite a few ways to cut clips or trim videos either in graphical or using command line tools. While video editors are heavy to do the job, FFmpeg is the most efficient choice. And Video Trimmer offers an intuitive user interface for those hate Linux commands.

It’s a free and open-source GTK app based on FFmpeg. By importing video via top-left “Open” button, you can preview the video and write down the start and end timestamps. And the top-left button turns to ‘Trim‘ for cutting the clip out.

It outputs the clip as a new video file. And the process is super fast and does not reduce the video quality, because it just cuts the data steam but never re-code.

Install Video Trimmer in Linux:

The source code of the project is hosted on gitlab. Besides building from the source, you can install it on most Linux via the Flatpak package.

For beginners, you can open terminal from start menu and run following commands one by one in Ubuntu to get the software.

1.) Install the flatpak daemon for running the app via command:

sudo apt install flatpak

2.) Add the flathub repository which hosts the software package by running command:

flatpak remote-add --if-not-exists flathub

3.) You can finally install the app via command:

flatpak install flathub org.gnome.gitlab.YaLTeR.VideoTrimmer

After that, open it from start menu and enjoy!

Uninstall Video Trimmer:

To remove the app as well as its data, open terminal and run command:

flatpak uninstall --delete-data org.gnome.gitlab.YaLTeR.VideoTrimmer
