How to Install Kode 20.1 in Ubuntu

Kodi website provides the downloads for all supported platforms.

For Ubuntu and Linux Mint users, the official PPA repository is one of the best choices to install the media play. So far, it supports Ubuntu 20.04, Ubuntu 22.04, Ubuntu 22.10, Ubuntu 23.04, Linux Mint 20/21.

sudo add-apt-repository ppa:team-xbmc/ppa

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

As a workaround, either run apt install command below:

sudo apt install kodi kodi-bin

Or run sudo apt full-upgrade to install all available updates (you may still need to install kodi-bin manually). For Linux Mint, run sudo apt update before doing updates!

The free open-source Android screen mirroring and remote control application, Scrcpy, released version 2.0 today!

The new release feature audio forwarding support! Meaning it’s not only mirroring your Android screen, but also sending the sound from Android to your PC speaker. The new feature supports Android 11 and higher. It’s enabled by default, though there’s --no-audio flag available to disable it.

Another big change in the release is that the device screen can now be encoded in H.265, or even AV1 if your device supports AV1 encoding.

The release also includes new --list-encoders option to list audio and video encoders available in the device, and --list-displays to list displays available on the device. For more about Scrcpy 2.0, see the official release note.

How to Install & Use Scrcpy in Ubuntu 22.04 to control your Android Phone Wirelessly or via USB cable

NOTE: This tutorial is tested and works in Ubuntu 22.04, though it should also work in all current Ubuntu releases.

Step 1. Prepare your Android device

To use the software, you need to first enable USB Debugging Mode in Android.

1. First, go to Settings in Android. Navigate to “About Phone”, and tap on “Build Number” several times (usually 7 times). It should prompt you something like “You are now in Developer Mode“.

TIP: there’s NO security issue or performance loss with developer mode enabled.

2. Then navigate to “Developer Options” in Settings menu or ‘Additional Settings’ sub-menu, and turn on the option for “USB Debugging“.

Step 2. Install adb

adb (Android Debug Bridge) package is also required for this software. Just press Ctrl+Alt+T on keyboard to open terminal and run command to install it:

sudo apt install adb

Step 3. Install scrcpy

There are few ways to install scrcpy, choose either one that you prefer.

Option 1: .deb package from system repository

Scrcpy is available in Ubuntu system repository. It’s working good in my case, though a little bit old that lacks new features.

To install the package, open terminal (Ctrl+Alt+T) and run command:

sudo apt install scrcpy

Option 2: Snap package in Ubuntu Software

The snap package in Ubuntu Software can be the easiest way to install the app, though it runs in sandbox.

The snap package at the moment is the last 1.25 version, though it will automatically update to v2.0 once maintainer updated the package.

Option 3: Install Scrcpy from the source

If you can’t wait to use the latest release, open terminal (Ctrl+Alt+T) and run the command below one by one to install it from source:

  • First, run command to install dependency libraries:
    sudo apt install ffmpeg libsdl2-2.0-0 adb wget gcc git pkg-config meson ninja-build libsdl2-dev libavcodec-dev libavdevice-dev libavformat-dev libavutil-dev libswresample-dev libusb-1.0-0 libusb-1.0-0-dev
  • Then, clone the source code via command:
    git clone
  • Finally, navigate to source folder and start the installer script:
    cd scrcpy && ./

    NOTE: After building process it may ask you to type user password for the permission to install files into system directories.

Step 4. Remote control your Android in Ubuntu

Now, connect your Android device into Ubuntu using USB cable. Then, click “Allow” in Android to confirm the “Allow USB Debugging” dialog.

1. First, open terminal (Ctrl+Alt+T) and start adb in your favorite mode:

  • To remote access via USB cable, run command:
    adb usb
  • To remote access using wireless network, run commands:
    adb tcpip 7676
    adb connect

    Here, change port number 7676 and the Android’s IP address accordingly! When done successfully, you can then remove the USB cable.

2. If the previous step goes well without any error! You can now start scrcpy:

  • Run scrcpy command in terminal if you installed from system repository.
  • Launch it from start menu (or ‘Activities’ overview) if installed from source. For debugging purpose, use scrcpy(console).

That’s all. Your android screen should appear in the Ubuntu desktop after launching scrcpy. Enjoy!

Uninstall scrcpy

To remove the adb package, open terminal and run command:

sudo apt remove --autoremove adb

To remove Scrcpy installed as .deb package, use command:

sudo apt remove --autoremove scrcpy

For the snap package, just use Ubuntu Software again to remove it.

And, for the package installed from source, navigate to the source folder again in terminal window and run command to uninstall it:

sudo ninja -Cbuild-auto uninstall

Peek, the popular animated GIF screen recorder application, has been discontinued!

It was one of my most favorite applications, that provides an easy to use interface for recording rectangle screen area into animated GIF.

The software developer announced that “With this announcement I officially declare the Peek project deprecated. This is something I should have done for a while now, but I always told myself that I will eventually do a last release, fixing some issues. As you know this never happened.

The big reason is because of Wayland. Peek is working good in Ubuntu 20.04, though it cannot record the top-bar. But Ubuntu 22.04+, Fedora Workstation and other Linux with recent GNOME have switched to Wayland that cause problems.

Wayland session does not provide the classic way that Peek uses to determine the recording area. It’s even not working properly when running as X11 app in Wayland via XWayland. The issue can’t be resolved unless completely rewritten the app in different UI in different way, but the developer is not interested in it.

However, Peek is still working in classic Xorg session that is default so far in most other desktop environments, and optional in GNOME. Though, it may have bugs and won’t receive fixes!

Alternative apps for recording animated GIF

As far as I know, Kooha is a good alternative that can record screen as GIF and supports Wayland session. And it’s available to install as Flatpak in Flathub repository.
