How to install flameshot version 9 or above on 20.04 LTS?

I'm using Ubuntu 20.04.03 LTS focal fossa.

Recently, I heard of a screen capturing tool known as Flameshot. I installed it on my system using:

sudo apt update
sudo apt install flameshot

The installation went well and I was able to use flameshot. However, in the GIF on the official GitHub page they have shown many features, such as numbers, margins etc...

But I am unable to use the "numbering feature" and a few more features. It seems like the version available in the focal repositories is pretty old and does not seem to have these features.

Is there any way I can get these features in Ubuntu 20.04 focal?

Apparently, you can compile the newer version of the package from source or install using Flatpak using the other answer

For compiling:

1. Satisfy Dependencies

   You need the following dependencies:

   Depends: libqt5svg5, libc6 (>= 2.14), libgcc-s1 (>= 3.0), libqt5core5a (>= 5.12.2), libqt5dbus5 (>= 5.0.2), libqt5gui5 (>= 5.10.0) | libqt5gui5-gles (>= 5.10.0), libqt5network5 (>= 5.0.2), libqt5widgets5 (>= 5.11.0~rc1), libstdc++6 (>= 5.2)
   

   Also, install the suggested packages:

   Suggests: git, ca-certificates, openssl
   

   You also need the following packages to compile:

   g++ cmake build-essential qt5-default qttools5-dev-tools libqt5svg5-dev qttools5-dev
   

   So, simply run the following commands in a terminal:

   sudo apt update 
   sudo apt install g++ cmake build-essential qt5-default qttools5-dev-tools libqt5svg5-dev qttools5-dev
   sudo apt install libqt5dbus5 libqt5network5 libqt5core5a libqt5widgets5 libqt5gui5 libqt5svg5
   sudo apt install git openssl ca-certificates
   

2. Get Source Code

   Get the source code of the package by cloning the GitHub repository:

   cd ~/Downloads
   git clone https://github.com/flameshot-org/flameshot.git
   

   Change the working directory to flameshot:

   cd ~/Downloads/flameshot
   

3. Building

   Run the following commands to create a building environment:

   mkdir build
   cd build
   cmake ../
   

   Now run the make command with sudo privileges and get ready for the installation:

   sudo make
   

4. Install

   N.B: It is really HARD to uninstall this installation. Only proceed if you want to install flameshot and are not planning to remove it in future

   Finally, run:

   sudo make install
   

Now you can see that the latest version is installed!

In 2022 we can avoid compilation by using Flatpak or Snap versions of Flameshot:

• Flatpak

  sudo apt install flatpak
  flatpak remote-add --if-not-exists flathub https://flathub.org/repo/flathub.flatpakrepo
  flatpak install flathub org.flameshot.Flameshot
  

• Snap

  sudo snap install flameshot
  

Appimage and .deb installers of the latest version are available at GitHub releases.
