I am using Mint Linux 15 Cinnamon. I want to install some applications using "Software Manager" (mintinstall). But when I start the "Software Manager" I get some of the weird code and at the last it says "Segmentation fault" in the terminal. When I try to open "Synaptic Package Manager", it starts up and crashes immediately after I give sudo password. Also I cannot use "GDebi Package Installer". This application too has the same problem. It starts and crashes immediately. I searched out for the problem but could not find any relevant answer. Please help me with my problem.
