$ sudo rpm--import http://li.nux.ro/download/nux/RPM-GPG-KEY-nux.ro

question : I want to try the shutter screen program on my CentOS desktop, but when I try to install shutter with yum, it always tells me "no shutter package available". How can I install shutter on CentOS?

Shutter is an open source (GPLv3) screen tool for Linux desktops. It packs a lot of user-friendly features, which makes it one of the most powerful screen programs in Linux. You can use shutter to capture a rule area, a window, an entire desktop screen, or even a Web page from any private address. In addition, you can use its built-in Image editor to edit the capture, apply different effects, export images to different image formats (SVG,PDF,PS), or upload images to a public image host or FTP site.

Shutter does not have a pre-built package on CentOS (up to version 7). Fortunately, there is a third party offering a Shutter package in RPM called Nux Dextop. So enable the Nux Dextop Software Library on CentOS and install it using the following command:

1. $ sudo yum --Enablerepo=nux-dextop install shutter
