I remember years ago that when I wanted to make some markings on my images, I did it by means of Shutter. The funny thing is that we are not talking about a software that is designed to mark, but it is a program whose reason for being is the screenshots, but its editor was so good that I installed it for that. Unfortunately, Canonical removed it from their official repositories to include Flameshot, another good tool, but without the powerful editor.
The problem Canonical decided to remove Shutter from its repositories seemed to be an outdated dependency, so its developer went ahead with the project, but more timidly. We could install it from a repository that also sidelined it, until Linux Uprising decided to hold out his hand and we can install it from your own. As the latter could change at any time, the good news is that Alan Pope has uploaded his Shutter to Snapcraft, which means that now we can install it from its snap package.
Shutter, great tool for screenshots with the best editor
One of the most important features of next-gen packages is that they include everything in one package, including dependencies. Therefore, they allow applications that have become obsolete to continue working, such as Shutter. The downside is that, sometimes, they do not work as we would like. In fact, this particular app has some faults or shortcomings, such as that the plugins are not compatible or that the icon does not appear in the system tray.
In any case, if you are like me and you used Shutter for its editor or dialing possibilities, now you can do it by opening a terminal and typing the following:
sudo snap install shutter
And if you have already forgotten about this app that had better times, you can always keep doing the dialing tasks with GIMP (that's how I do it now) or use other tools like ksnip that are in the repositories of some Linux distributions. Now that Shutter is back, the decision is yours.
