Sofware Updater has the wrong repositories

[Bingo Bones]

[My apologies if this isn't the correct section in which to add this post. I wasn't sure where it should go.]

When I boot up Freya there's a red indicator in the panel telling me that there's an error with the repositories. I've tried using the indicator to install updates but nothing happens.

I opened the software updater settings and saw that everything seems to be connected to Debian Jessie rather than Ubuntu Trusty.

I've tried a number of simple fixes via the terminal but nothing helps.

There's probably some simple solution, and it's probably my stupid fault in the first place.

Any suggestions much appreciated.
