Update 2
In ubuntu 18.04, flameshot can be installed directly
sudo apt install flameshot
Update
There is a ppa for this now. Follow the below link
https://launchpad.net/~harish2704/+archive/ubuntu/ppa1
First check whether you have git installed
sudo apt install git
Clone the repository using this command
git clone https://github.com/lupoDharkael/flameshot.git
Go to the clone directory
cd flameshot
Install the dependencies
sudo apt install -y git g++ build-essential qt5-qmake qt5-default qttools5-dev-tools
Compile and install using qmake and make install
qmake
make install #desktop entry fails with warning
To use it
flameshot gui #via terminal
Enjoy smile
To use it on keyboard shortcut just add an shortcut calling “flameshot gui” and the prntscr button (working on ubuntu 16.04)
All the above steps followed by me and finally there is no result.
There is a ppa now. Isn’t it working? I will update the post after checking them.
On 16.04 qmake will fail
