Download XnSketch for Linux

After downloaded the package, just decompress, then click run the “XnSketch” file from the extracted folder will launch the application.

If you like this app, and want to add it to system start menu or Gnome app grid, then do the following steps one by one:

First, move the app folder to a desired location for long time use. In my case, I created a “MyApps” folder in user home, and put these apps folders there.
Then, navigate into the XnSketch app folder, and click edit the “XnSketch.desktop” file.
When file opens, replace the values of “Exec” and “Icon” according to where you moved the app folder (press Ctrl+L in that folder then copy).
Finally, press Ctrl+Shift+S to open ‘Save as’ dialog, and choose save the file into .local/share/applications (press Ctrl+H to view hidden folders) directory.
