In order to get Debian back to the way it should be, you'll need to make some changes to apt. Don't worry - it's quite simple. First, you'll need to boot up your console and get to a root shell - Doing this depends on how you've set everything up, though the default Debian install should boot right into one. If you've added a desktop environment, look for a terminal program - If you can't find one, you can switch to a built-in console by pressing Ctrl+Alt+F2 (or any F key between 2 and 6) and logging in as root.Once you're in, you'll need to open "/etc/apt/sources.list" in a text editor. Debian-wiiu ships with nano, so you should type the following:You may have changed this file a bit, but the default one looks like this:If you have the heyquark line, you should comment it out by adding a "#" to the start of the line. It'll make updates a lot faster since I haven't got that repository online at the moment. Anyway, what we actually need to do is change whatever URL is before "sid main" (some may have changed it, I hear ftp.debian.org is popular) to " http://ftp.ports.debian.org/debian-ports ". After this is done, the file should look something like this:Next, you'll need to teach apt to trust ports.debian.org. If you jump straight in you'll start getting strange errors about public keys, so we need to sort all that out first. You can do it with a single command:That's a capital O (as in "boop"). You might have to update the year on the end of that URL if you're reading this in the future. You'll get a bunch of output, finishing with "OK". Once that's done, run the following two commands:You're now good to go! Since you probably haven't updated your packages in a while, it'd be a good idea to run apt-get upgrade as well. You can now update and install packages again without any problems!
