Software Manager: This is graphical interface for managing applications on Linux Mint. For new users, it is a more user-friendly interface for installing applications, more so than using apt-get, the command-line client.

In this latest edition of Linux Mint, the software Manager did not see any improvements, but that still does not take anything away from its user-friendliness. Whether you are using the MATE or Cinnamon editions of Linux Mint 15, you get the same graphical application manager. The main interface is shown below.

The Software Manager has often been criticized as too slow to load, and it is still slow to load, compared especially to Deepin Software Center of Linux Deepin. Overall, it is still faster than Apper, the graphical package manager of Fedora.

A new graphical management application that made its debut in Linux Mint 15 is the Software Sources manager. It provides a unified interface for managing various aspects of the repository; from adding or removing repositories, to managing authentication keys. With this tool, it is no longer necessary to use add-apt-repository to add a Personal Package Archives (PPA) from the command-line.

A problem I observed with Software Manager is that when the Software Sources window is open (from Edit > Software Sources), then closed, Software Manager crashes, and then restarts automatically. This is reproducible every single time on the MATE and Cinnamon editions. Interestingly, when both windows are open, you can close Software Manager and the Software Sources window still remains open.

The other side to the crashing of the Software Manager is that no bug reporting tool is automatically launched to make it easier to file a bug report. On Fedora, when an application like that crashes, abrt-gui, a graphical interface to abrt (Automatic Bug Reporting Tool), is started automatically. In Linux Mint 15, the package is not even in its repository. But whoopsie, a bug reporting application that works similarly to abrt, is in its repository, but not installed. In Ubuntu (13.04), Linux Mint’s parent distribution, that bug reporter is installed and running. Sometimes I think that there’s a good reason distro developers switch off certain features. However, in this case, I can’t think of a good reason why whoopsie is not installed and configured.

Security Profile: All Linux Mint 15 editions – MATE, Cinnamon, KDE, and Xfce, have the same security profile and posture. Aside from the physical security features which was discussed earlier in this review, they also have the same network security posture. The firewall application, ufw, is installed and the daemon running, but the firewall is not enabled.

For managing the ufw firewall, there is a graphical interface called Gufw, which is not installed, but is in the repository. Once installed it just has to be enabled and you have a simple interface for managing the firewall.

Though ufw and Gufw are easy and simple to use, I found that a more powerful firewall application is in the repository. This application, called Firewalld, is the new (as of Fedora 18) firewall application in Fedora. Firewalld brings a lot more features to the table than ufw, and firewall-config, its graphical interface, is more feature-rich than Gufw. I’ve been able to replace ufw with Firewald in Linux Deepin and Linux Mint 15 Cinnamon. So far, I’ve not observed any problem(s) wit both installations. (See How to customize Linux Deepin 12.12 and How to replace Ufw with Firewalld in Linux Mint 15.)

Aside from the firewall, there is not other network security management application installed, even though packages for the 3 application-level “firewalls” for Linux distributions are in the repository.

New desktop environments like Cinnamon and Depth (Desktop Environment) of Linux Deepin appear to have started what could be termed fragmentation in the desktop environment space. However, I don’t think it’s going to be as bad as the fragmentation of Linux distributions that diluted the talent pool available to so many Linux distributions, giving us hundreds of distributions that don’t bring anything new to the table. With the new desktop environments, of which Cinnamon is about the most popular, I see a lot of new ideas and new feature being brought forward.

If you are using Linux Mint 15 Cinnamon, you can already see some of those features in the graphical management applications that have been coded with non-geeks in mind. And this is what we should be rooting for, which is why Linux Mint is one of my favorite distributions, never mind the poor security posture that it presents out of the box.
