Flameshot is a simple yet powerful screenshot tool with annotation feature. Other than Shutter, it’s another of my favorite screen capturing tools for Ubuntu desktop so far.

Flameshot is written by C++ with Qt5 framework. It offers a system tray icon with ‘Take Screenshot’ and ‘Configuration’ menu options.

While selecting a screen area to capture, many editing tool buttons appear at the bottom. And you can press right-click to show color picker, and Space to open the side panel.

Other software features include:

  • Customizable appearance.
  • DBus interface.
  • Upload to Imgur.

How to Install Flameshot in Ubuntu:

The software is available in Ubuntu Software for Ubuntu 18.04 and higher, however, Canonical won’t provide regular update for the package.

For the latest release, grab the .deb package for Ubuntu 18.04 bionic or Ubuntu 16.04 xenial from the link below:

Flameshot releases

then right-click the .deb package -> Open with Other Application -> Gdebi package installer. (install gdebi via command sudo apt install gdebi in terminal).

Uninstall:

To uninstall the tool, open terminal either via Ctrl+Alt+T shortcut key or from software launcher. When it opens, run command:

Linux Kernel

There’s already a graphical tool called Ukuu which make it easy to install the latest Linux Kernels in Ubuntu and Linux Mint.

Today I’m going to show you a new command line tool called UKTools which provides:

  • uktools-upgrade, one command to install the latest Linux kernel (stable) from kernel.ubuntu.com.

  • uktools-purge, one command to remove old kernels, the first and the last two are excluded.

The tools also support cron jobs to automatically run upgrade and/or purge scripts.

NOTE that the mainline kernels are provided by Ubuntu Kernel Team for testing and debugging purposes. They are not supported and are not appropriate for production use. You should only install these if they may fix a critical problem you’re having with the current kernel. Read more about mainline kernels.

How to Install UKTools in Ubuntu:

The application does not has any Ubuntu binary at the moment. However, it’s easy to compile it from the source.

1. Open terminal (Ctrl+Alt+T) and clone the source via command:

git clone https://github.com/usbkey9/uktools && cd uktools

2. Then compile and install it via command:

make

The setup runs automatically if it’s installed successfully.

Uninstall:

Keep the uktools folder in your user root directory, so you can re-run UKTools setup, or remove the command line tool via command:

cd ~/uktools/ && make uninstall
