Can't install anything other than 'sudo' because of the error package not found Anyone have any ideas? I'm posting here because nearly all of my issues have been fixed, mainly wanting to install Steam and some other applications such as leafpad. Keep in mind, I have been using Ubuntu, but recently changed to Debian, just to try it out.If you need further information just leave a comment, thanks. By the way, I've checked every single other similar questions and none of them help.Debian Jessie 8.6Error:$ sudo apt-get install <package>Reading package lists...
