Ok, I'm new to this and failing miserably. I'm trying to install k9copy onto Debian Crash-Bang, and have downloaded the latest version from their site: k9copy-2.3.7-Source(1).tar.gz
Synaptic doesn't find k9copy, so I've been trying apt-get and dpkg command lines in the terminal. Every installation guide I've read says to try # sudo apt-get install package-name so I've tried # sudo apt-get install k9copy, # sudo apt-get install k9copy-2.3.7.tar.gz, and every variations thereof, but all get:
E: Unable to locate package k9copy.tar.gz
E: Couldn't find any package by regex 'k9copy.tar.gz' ......whichever I tried. Would appreciate anyone being able to explain to me in dunce language where the folder is having downloaded it and how to turn it into a working program.
