I am new in Linux and debian 10 (KDE) is the first distribution that I am using. But when I'm trying to install atom editor when I use this command It gives me an error : command >> sudo apt-get install atom Output : Reading package lists... Done Building dependency tree Reading state information... Done E: Unable to locate package atom I looked it up in google but i couldn't find anything to fix my problem.
