So I got this PPA to install this application mentioned here : http://shutter-project.org/faq-help/ppa-installation-guide/
But when I add it and attempt to update, it throws a 404.
Is there any way I can install this awesome screenshot tool in Lubuntu 18.10?
Note - I noticed that on the official page there is a tar file but I really want to keep the app updated. Besides when I download it it throws errors about unmet dependencies regarding Gnome.
