A Linux Mint user can install a new application on their system using Software Manager, Synaptic package manager, or command line terminal. Beginners prefer using software manager over command line terminal and synaptic because of it’s easy user interface. One can also see the application ratings and user reviews from Software Manager.
Software Manager is already present in Linux Mint ( Linux Mint 13 ) by default. If you still don’t like, you can go for Ubuntu Software Center as a better option.
To install, open the Command terminal ( Ctrl+Alt+t) and type the following command:
sudo apt-get install software-center
If it doesn’t work, then first run the system update using following command then again type the above command:
sudo apt-get update
Although, Ubuntu Software Center and Software Manager are easy to use but Command line terminal and synaptic package manager gives you full control.
